Year of the Rabbit – Rabbits in art

To celebrate the Chinese New Year and the start of the Lunar New Year on the 22nd January we thought we would look at the rabbit, our friendly bunny.

So, what might we expect from this new year?

The rabbit is a symbol of longevity, peace, and prosperity in Chinese culture. 2023 is predicted to be a year of hope. People born in a Year of the Rabbit are believed to be vigilant, witty, quick-minded, and ingenious.

Rabbits have been seen as a symbol of sex and fertility since antiquity. In ancient Rome rabbits were frequently depicted as the animal of Venus. Conversely the rabbit was used by artists of the Middle Ages and Renaissance as a symbol of sexual purity and was often depicted alongside the Madonna and Child.

For those wanting to celebrate the Year of the Rabbit, you can purchase a £5 gold coin from The Royal Mint. If you have something more elaborate in mind, Christian Dior have produced a watch for this auspicious year, which retails at £29,000.

We could, however, simply celebrate the role of the rabbit in art over many centuries. See how the furry creature has inspired artists throughout the years.

Wishing everyone a Happy Year of the Rabbit.

A review of the December Old Master Sales in London

December is an exciting month, not just because Christmas is coming, it is also the last hurrah for the Old Master Painting season in London. Sotheby’s had the better pictures and therefore, the better of the results. Their Day Sale (lesser fry) at a total of £3.34M was roughly three times the value of Christie’s at £1.185M. Furthermore, Christie’s had a large total of lots unsold on the day, 40 out of 104 lots.

The Evening Sale (the top lots) followed a similar pattern with Sotheby’s sale to talling £32.72M, with Christie’s coming in at a more modest £13.14M. In fact, Sotheby’s top lot, Titian’s ‘Venus and Adonis’, at £11.1M made almost as much, on its own, as Christie’s whole sale.

They had a beautiful still life by the Haarlem painter Floris van Dijck, very similar in composition to the painting in the Rijksmuseum and one of my favourite pictures in that collection. This made £2.09M against a pre-sale estimate of £600,000-£800,000.

Also estimated at £600,000 – £800,000 was a dramatic seascape by Ivan Konstantinov Aivazovsky titled ‘The Wrath of the Seas’. I was particularly interested to see what happened to this painting, by a 19th Century Russian artist, bearing in mind what is going on in Ukraine. On the day it made a very healthy £1.729M, proving that Aivazovsky has an international reputation and is not just for local consumption!

During the view at Christie’s, I was intrigued to speculate what would happen to two portraits, in particular. The first was a portrait of Erasmus by Hans Holbein the Younger, court painter to Henry VIII and the second was, to my mind, a very beautiful portrait of Henrietta Maria, by Sir Anthony van Dyck, court painter to Charles I.

In the event, they both disappointed with the Holbein making £1.12M against an estimate of £1-1.5M and the Van Dyck limping away at £2.44M against an estimate of £2-4M. The highest price was £2.92M (estimate £2-3M) for ‘Reading Party’ by the French Rococo artist Jean Francois de Troy.

These sales told us nothing new about taste for Old Masters, but they did reinforce what I said in July and that is that there is keen interest in paintings by good hands, fresh to the market and in good state. Selling lesser things, which have been seen before, is a struggle.

The Paul Allen collection

In the same way that ‘location, location, location’ has historically underpinned great property investment, ‘quality, quality, quality’ has always lain at the heart of great art collecting. The strength of this strategy of only buying the very best proven crystal clear with the spectacular results achieved by the recent auction of the art collection amassed by the late Microsoft co-founder, Paul Allen’s at Christie’s.

Split in two parts – Visionary: The Paul G. Allen Art Collection, was provocatively billed by Christie’s in their pre-sale marketing, ‘to be the largest and most exceptional art auction in history’, with predications that it would surpass $1 billion in sales for the first time in history, beating the $922.2m realised last by Sotheby’s in May last year’s Macklowe Collection.

Christie’s predictions turned out to be both true and conservative – Part I of the collection on 9th November saw 60 extraordinary works achieve a total of $1,506,386,000, with five paintings achieving prices above $100 million. The works in the sale sold 100 per cent by lot with 65 per cent of the lots selling above their high estimates. Part II of the collection on 10th November, went on to achieve an additional $115,863,500 for the remaining 95 works offered for sale. In total, the proceeds for the landmark series of sales, totalled and an extraordinary and ground-breaking $1,622,249,500 – all of which is being donated to the various charitable causes Paul Allen established and supported during his lifetime.

What makes the Allen collection so extraordinary, aside from the huge numbers attached to it, is that the collection was put together entirely by Allen himself in less than 30 years. The fact that a collection of such quality and size can still be amassed today, with so many masterworks being in museum collections and out of commercial circulation, is remarkable.

The scope of Allen’s collection is unusual in that it spanned more than 500 years, from Botticelli to Monet, from Picasso to Stella, from Seurat to Hockney. This breadth and variety of collecting is increasingly rare in today’s world, when most collectors tend to focus on a specific area of interest or particular artists, and develop collections which, although important, are more limited in their reach. Paul Allen’s collection and his method of collecting harks back to the height of American collecting in the late 19th and early 20th centuries when legendary collectors such as Frick, Rockefeller and Getty scoured the world for masterpieces across all genre and eras – the only prerequisite being quality. This type of collecting is a truly American phenomenon and demonstrates that when there is the rare combination of ambition, taste and limitless money, great things can happen.

What sets the Paul Allen Collection apart from others is the also fact that Allen himself oversaw each and every purchase himself, without the help of the ubiquitous art advisor who is the mainstay of most billionaire collectors. This personal engagement in the collection, reflects Allen’s strong interest in world culture and history, and gives the collection a personality which only great collections possess. As Paul Allen said, “When you look at a painting you’re looking into a different country, into someone else’s imagination, how they saw it.”

It was a given that such an extraordinary collection was always going to achieve extraordinary things when offered at auction – since the market is avaricious for works of this level. Christie’s performed their part superbly, and ran a slick international marketing campaign that promoted the collection worldwide. The results were stupendous.

The highest price achieved in the sale was for Georges Seurat’s 1888 Pointillist masterpiece, Les Poseuses, Ensemble (Petite version), which made $149.2m and smashed the previous Seurat world record by a multiple of four. The world icon is used far too often in modern parlance, but in this case, the word is truly deserved.

Similarly, Paul Cézanne’s 1880-1890 La Montagne Sainte-Victoire – a classic rendering of Cézanne’s most iconic of subjects – also smashed the $100m barrier, achieving $137.8m; and Gustav Klimt’s 1903 painting, Birch Forest, set a world record for a Klimt, selling for $104.6m.

Other notable sales included the highest price ever for a van Gogh painting, Verger avec cyprès, which sold for $117.2m. Paul Gauguin’s 1899, Maternité II made $105.7m, and Lucien Freud’s masterful portrait, Large Interior WII (after Watteau), made $86,265,000.

Further paintings by Éduard Manet, Pablo Picasso, David Hockney, Andrew Wyeth, and Georgia O’Keeffe, all went onto achieve strong prices, alongside sculptures by Alberto Giacometti, Alexander Calder and Max Ernst.

In contrast to these masterpieces of Impressionist and Modern Art, the collection also featured a number of significant old master paintings – most notably, Sandro Botticelli’s exquisite, Madonna of the Magnificat, which sold for a ‘relatively’ affordable $48,480,000m, when one considers the rarity of fully autograph works by Botticelli on the market.

One work, Lot 131, demonstrates to me more than any other work, the personal nature of the collection, and the discerning eye of the Paul Allen himself. It also happens to be the most modest work offered for sale. Measuring only 21cm high, it is an exquisite but fragmented Renaissance sculpture showing clasped hands of the Virgin Mary, catalogued as Circle of Donatello. The fact that a man such as Allen, who could afford any masterpiece in the world, was also drawn to such an exquisite but unassuming work, indicates the level of his sophistication, and proves that quality, should lead a collector when buying a work. The market agreed, and the little gem made 26 times its lower estimate and made $252,000.

Winslow Homer

I went to the Winslow Homer exhibition at the National Gallery last week and strongly recommend it to you. It is the first time his work has been shown en masse in the UK and there are no paintings by him in British Public Collections, despite his being a household name in the USA.

He started life painting scenes from the American Civil War and much of his work describes conflict, racial tensions, and other social problems. He also had a real obsession with the sea and spent nearly two years on the Northumbrian coast at Cullercoats, observing and recording the activities of the local fishing community and its struggle with the sea. For Homer, the sea was a source of pleasure, livelihood and terror depending on its mood. He painted numerous scenes of people being rescued from the tempestuous ocean.

I was very struck by a painting executed in 1904, which shows three men wearing sowesters and waterproofs in a rowing boat where the swell is so immense you can’t see the boat , and its title is ‘Kissing the Moon’. It reminded me of a passage in Joseph Conrad’s novella ‘Typhoon,’ where the waves are so great the characters in the boat see the moon disappear below the horizon and when it returns to view, appears to be dripping water. I wondered if this book could have had an influence on Winslow, so I googled it! Conrad began the novel in 1899 and it was subsequently serialized in Pall Mall Magazine between January and March 1902. It was first published in book form by Putnam in New York in 1902, two years before Winslow Homer painted the picture. I think I have answered my own question.

Winslow Homers don’t come up for auction very often, only 68 in the last 35 years. The world record for him (at auction ) was achieved in November 2014, by Sotheby’s in New York, when Mrs Paul Mellon’s ‘Watching the tide go out’, a tiny canvas, just over 12 x 16 in , made $4.5m.

An introduction to NFT’s for brokers – with Jonathan Horwich, Art specialist & Alastair Meiklejon, Senior Valuer

NFT’s are the latest trend in the art world, but many people do not understand them.

  • What are they?
  • How do they work – how do you “use” them?
  • Why do artists make them?
  • Why do collectors collect them?
  • How are they priced, sold and valued?
  • Are they worth anything?
  • What are the risks in buying them?
  • Can they be insured?

Marilyn Monroe – Shot Sage Blue Marilyn

She was THE film star of her day, and at the auction on 9th May 2022 at Christie’s New York, she proved that her star power was as strong as ever!

In under four minutes of bidding, Andy Warhol’s 1964 painting of Marilyn Monroe, Shot Sage Blue Marilyn, sold for $195,000,000 to an unknown buyer, making it the highest price achieved for any American work of art at auction – comfortably beating the world record of $110,500,000 that Basquiat’s Untitled, 1982 made at a Sotheby’s auction in New York in 2017.

Described as ‘the most significant 20th-century painting to come to auction in a generation’, Shot Sage Blue Marilyn is one of only 5 works Warhol produced in this series – each in different colour variations.

The paintings were stored at The Factory, his studio on East 47th Street, Manhattan. It was here that the artist, Dorothy Podber, stopped by and asked Warhol if she could “shoot” them. Presuming she meant with a camera, he said yes, but instead she pulled out a revolver and shot all but the turquoise print in the forehead! Warhol had the four paintings restored and they became known as the “Shot Marilyns.”

The work was the undoubted and much-anticipated star lot of the Christie’s Monday sale, which itself kicked off New York’s spring season of mega auctions. As such, it was always going to attract huge interest, eventually selling to Larry Gagosian for an undisclosed client.

The sale itself was made up of 36 lots consigned from the estate of the legendary Swiss dealers Thomas and Doris Ammann, with all of the proceeds going toward their foundation, which supports health care and educational programs for children. Interestingly and very old school in approach, none of the works were backed by financial guarantees, which is a system whereby the auction houses provide sellers with a minimum price at which a third party or the auction house has committed to purchase the work even if it fails to sell on the day.

Perhaps a risky approach one might think, however, after 2 years of pent-up demand from collectors, and with huge amounts of money sloshing around, and with such star works on offer, it was a risk well worth taking, with the overall sale achieving $318,000,000 for the Ammann charitable foundation. Lucky them!

It all goes to show that quality will always win out, and the best works will always achieve the strongest prices. That said, having Marilyn on your side can’t hurt either!

If I had £5,000 to invest what would I buy?

£5,000 to buy art – sounds wonderful, doesn’t it? It is certainly a decent chunk of change to play with – large enough to focus the mind and to open the possibility of buying something a little bit more special than a decorative wall filler. Conversely, the moment one starts looking at works in a slightly higher price bracket, and by artists who have more pedigree, suddenly £5,000 doesn’t seem that much at all! A strategy is, therefore, needed if the canny buyer is to maximise their buying power.

For me, if I had £5,000 to spend on one artwork, I would adopt a twofold approach – firstly I would look to buy as good a work on paper as I could find by an artist whose work I loved, but whose paintings are out of my reach. Secondly, in order to maximise my buying power, I would concentrate my search entirely on the auction market rather than buying from a retail gallery. Buying from auction can take a little more time, and it needs a little more research by the collector, but it often allows one to buy works considerably cheaper than retail level. As a famous supermarket says – every little helps!

The artist I would buy with my £5,000 is an artist who I think is significantly undervalued in the current market, both in terms of his talent as well as in comparison to the values many of his contemporaries achieve. Keith Vaughan is a relatively overlooked Modern British artist who was born in 1912 at Selsey Bill in Sussex. He was a self-taught artist with no formal instruction in art, yet he went onto forge a highly individualist and distinctive career which has until fairly recently has been overshadowed by the giants of his generation – Henry Moore, Barbara Hepworth, Terry Frost, Ivan Hitchens etc.

Vaughan started his career as a commercial artist when he was apprenticed at the Lintas advertising agency, from which he gained an understanding of composition and form – both essential skills in commercial art. From 1939, after he left Lintas, Vaughan became a full-time artist. With the outbreak of World War II, Vaughan declared himself a conscientious objector and joined the St John Ambulance; in 1941 he was conscripted into the Non-Combatant Corps.


During the war Vaughan formed friendships with the painters Graham Sutherland and John Minton, with whom after demobilisation in 1946 he shared premises. Through these contacts he formed part of the neo-romantic circle of the immediate post-war period. However, Vaughan rapidly developed an idiosyncratic style which moved him away from the Neo-Romantics. Concentrating on studies of male figures, his works became increasingly abstract.
Vaughan worked as an art teacher at the Camberwell College of Arts, the Central School of Art and later at the Slade School.

Throughout his life, Vaughan’s struggled with his own internal demons. Keith Vaughan was a gay man living in a time when homosexuality was illegal and actively frowned upon by Society. His struggle with his sexuality is reflected throughout his work and in his source of subject matter. Studies of figures and male nudes feature heavily in his work, although they are simplified and abstracted showing the influence of both international Modernism, Cubism his love of ballet and dance. Vaughan suffered from habitual depression and alcoholism, which eventually resulted in his suicide in 1977.

One might be forgiven for thinking that in light of all this Vaughan’s work would be negative and dour, however, this is wrong. As is often the case, personal struggles can produce works of great sensitivity and subtly. Vaughan’s work has a graphic quality that is softened by the use of a very sophisticated colour palette. They are very beautiful, elegant images.

The commercial art market has begun to reflect the increasing interest in, and appreciation of Vaughan’s work, with good examples now regularly achieving six figure sums at the auction. His works are also appearing more frequently at high end art fairs, where wall space has a commercial value, and a dealer’s decision to show a Vaughan instead of another artist is a calculated strategy, and one that reflects growing demand.

And yet, even with this increased visibility Keith Vaughan’s work is still undervalued in relation to many of his contemporaries, and it represents significant investment potential. His drawings in particular are surprisingly accessible financially and it is entirely possible to buy lovely pencil or pen and ink studies for a thousand or two, sometimes less; and more important, finished watercolours and gouaches can be bought within our £5,000 budget at auction.

How long this relative accessibility will last, I cannot say, but in my opinion now is definitely the time to buy Keith Vaughan’s work if like it and respond to it. Clearly, as always, liking an artist’s work is the primary reason for buying it, but it’s always nice to have a healthy upside too.

Sir Terry Frost, 1915-2003

To be asked to write an article about one of my favourite artists is truly a delight. Sir Terry Frost’s muse wasn’t a person but the Cornish town of St Ives. Thanks to Covid this unique seaside town with all its artistic heritage, glorious light, sights and sounds of the sea, which was for so long an inspiration for Terry, is now the ‘go to’ vacation spot for families across the UK, so hopefully current and future generations will get to see for themselves just what inspired Terry and so many other great artists over the years.

Terry was born and brought up in Warwickshire, he left school at 14 and started work locally, working mostly manual jobs with no sense that his natural artistic ability would ever make him a living. When war came he served as a regular soldier, first in France then the Middle East and Greece before joining the Commandos. While serving with them in Crete in June 1941 he was captured and sent to various prisons for the duration of the war. During his time at Stalag 383 in Bavaria, he met the painter Adrian Heath who saw Terry’s talent and encouraged him to paint. Terry later described these years as ‘a tremendous spiritual experience’, he felt that he had gained ‘a more aware or heightened sense of perception during my semi starvation.’




As soon as the war was over, Terry went to study at the Birmingham College of Art, he soon discovered the action was in London and moved down to Camberwell School of Art. By 1946 he had removed to study at St Ives School of painting for one year where he held his first one man exhibition in 1947. He continued his studies in London and Cornwall and when in 1950 he was elected a member of the Penwith Society, he made a move to St Ives in 1951. He later taught at Leeds and in Cyprus and finally settled in Banbury, Oxfordshire in 1963.
In 1960, Frost held his first one-man show in New York at the Bertha Schaefer Gallery. This exhibition was a seminal moment in his career and he said of this experience:
In New York they all came to my exhibition, de Kooning, Rothko, Klein. Newman and Motherwell all took me to their studios.

I accepted it all as normal and they accepted me. They were all painters struggling to get somewhere like I was. They worked hard; they would sleep until noon, do eight or nine hours in the studio, and then starting at eleven at night proceeded to drink me under the table! Then we’d go out at four in the morning and have breakfast at a Chinese restaurant.’

I first met Terry in the 1980’s during my early days at Christie’s, I would see him either at our auction preview ‘Drinks’ or at his shows at the Whitford gallery just around the corner in Duke Street. He was always full of fun and told great stories such as this one from his days working in the 1950’s as an assistant to the sculptor Barbara Hepworth in her studios in St Ives … Hepworth was convinced her clients would not buy her work if they knew she didn’t make everything herself, so she was understandably nervous whenever prospective clients came to visit her studios. Terry told me that whenever visits took place he and the other assistants all went down to the pub until the coast was clear. One particular day important clients were coming so Terry and the other assistants made themselves scarce in the pub as usual, expecting on their return to find the visitors long gone. However as soon they arrived back Barbara told them to hide, the clients has arrived late and were still in the house and would be coming up the path any minute now. The assistants all managed to quickly find a hiding place and Barbara began showing the clients around the garden and studio. Terry was well hidden behind a bushy tree, however he could feel all the beer was beginning to well up inside him and very soon he was going to have to pee ! He hung on and on but with the tour continuing he could hold out no longer. He couldn’t risk nipping to the loo so performed the task from his bushy hiding place thinking he had got away with it. However unknown to Terry he had unwittingly created a small river which was running swiftly down the path towards Barbara and her prospective clients, Barbara noticed the stream but luckily her clients were too busy enjoying their tour to notice and Terry got an ‘earful’ from the boss after they had gone.


Terry’s many talents were fully recognised during his long career, he was made an R.A. in 1992 and Knighted in 1998. Speaking in the 1980’s about his work he said; ‘A shape is a shape, a flower is a flower.

A shape of red can contain as much content as the shape of a red flower. I don’t see why one should have to have any association, nostalgia or evocation of any kind. It boils down
to the value of the shape and the colour.’
Terry was always making art and exploring new avenues and mediums. I went to his last London show at the Whitford Gallery to see he had totally changed his medium and had made wonderfully colourful moulded and blown glass pieces. Forever energetic and full of new ideas, Terry Frost represents all that is good and great about late 20th century British Art.

You have £5,000 to spend – David Oxtoby prints

How Would I Invest £5,000? By CEO and Old Master Specialist, David Dallas

If my godfather left me £5,000, I wouldn’t hesitate to spend every penny buying the suite of etchings (24), which David Oxtoby produced in 1974.

David Jowett Greaves Oxtoby is undoubtedly one of Britain’s greatest printmakers, as the show at the British Museum proved two summers ago. He was one of the notorious ‘Bradford Mafia’, a group of young Yorkshire artists, who after attending the Regional College of Art in Bradford, came to London to further their education at the Royal College of Art and The Royal Academy schools. As well as Oxtoby, the group included David Hockney, Norman Stevens A.R.A, John Loker and Mick Vaughn. Before he had left the Royal Academy schools, Oxtoby had his first one man show in New York. His was and is a prodigious talent.

By the early 1970s his hands were starting to crack, and he was told that he was allergic to the acrylic paints he was using. After taking medical advice, he took up etching and what a triumph that was. In collaboration with J.C. Editons he produced a suite of 24 immensely complicated, in some cases, 4 colour, etchings. I have the good fortune to own a set of artist’s proofs.

‘The Man’: Stevie Winwood. Signed, inscribed and dated ‘74. Published Sept ‘74. Artist’s proof for an edition of 50. 4 colour etching on handmade English paper. Plate size: 335 x 115 mm

In 1974 I worked for Alex Postan Fine Art and was entrusted with getting publicity for the show of etchings, which included watercolours and acrylics as well as prints. It was the easiest job I have ever had. Marina Vaizey wrote a half page review of it in The Telegraph, Bill Packer, a half page in the Financial Times and it was in the list of the 10 best things to do this Christmas in London in the Daily Express. Rod Stewart came to the private view.

Oxtoby went on to exhibit with the Redfern Gallery in Cork Street in the 70s where the private views would sell out. Elton John bought Oxtoby’s canvases in vast numbers, for prices that were somewhere between Hockney and Picasso. He is still with the Redfern.

He has had more than 50 solo exhibitions and taken part in more than 70 group shows, yet for much of the last 30 years has lived like a recluse and kept all his latest work from public scrutiny. The result of this has had an adverse effect on the value of his work.

Oxtoby has not had the recognition for the brilliance of his draftsmanship and use of colour from the establishment that his oeuvre deserves. This seems to be because his work is inspired by popular culture, pop, rock and blues music, which is considered low brow and because he works from photographs, despite knowing subjects like Jimi Hendrix, George Harrison and Roger Daltrey well.

He was 82 in January and is not in good health. The cracked hands, which turned him into a printmaker, were actually caused by misdiagnosed diabetes. What future generations will make of his work remains to be seen, but I believe he is ready for a critical re-assessment and should take his rightful place amongst the greats of late 20th/early 21st century British art.

Caring for Paintings

Pictures, like small children, prefer consistency of treatment. In the case of caring for paintings and watercolours this means no violent fluctuations in temperature or humidity.

Water damage

If you have a damp room a de-humidifier can bring the relative humidity down around 40%-60%, above this level and there is a possibility of mould growing on surfaces and this can stain the paper on which watercolours, drawings and prints have been worked, irrevocably. Some moisture in the air is good, especially for inlaid furniture and panel pictures. I was in the Pinacoteca in Bologna 40 years ago, where there was about zero relative humidity and the great wooden altarpieces were groaning like ships’ timbers, as they dried out and moved. It is not like that now!

Example of water damage

Example of water damage

Where to hang your painting

Hanging paintings above radiators or chimney breasts is to be avoided as the paint layer dries out and becomes brittle and if the painting is on a panel it can warp. The same applies to furniture.

A light-damaged painting

A light-damaged painting

Direct sunlight is a no-no, especially for watercolours. I remember seeing a large pair of watercolours by Turner hanging in a lightwell. They had been there since 1800 when the owner’s forbear had bought them at Christie’s. I tracked the sale and instead of being worth £200,000 (they were obviously very early ones) they were worth about £5,000 as curiosities. All the colour had been bleached out – no blues, no greens, just pale pink and brown smudges. What a tragedy!

Whether light travels in waves or pulses, it equals heat, and this will damage anything subjected to it. Ultraviolet inhibiting strips can be put on windows, but they are only about 60% effective and should not be exclusively relied upon. Old-fashioned velvet curtains, with brass rods stretched through the bottoms are an ideal way of protecting watercolours in daytime and can be turned back at night.

Artificial lighting can be harmful too, although it lacks the sun’s power, so low energy bulbs should be used and try to avoid picture lights on brass arms attached to the frame of an oil painting. They are too close to the surface of the painting and can cause stress to an old carved and gilded frame.

Cleaning of paintings

The cleaning of all paintings must be left to well-trained professional conservators. It is a highly complex procedure requiring in-depth knowledge of chemistry. Never use a damp cloth to clean the gilding on a frame. If it is water-based gilding, as opposed to oil, it will dissolve. A feather duster is preferable to a cloth duster as it is less likely to snag the carving and pull it off. You can dust the surface of an oil painting, very gently, with a cloth duster.

Lastly, never dust the glass on a pastel, it can cause static electricity to build up and the pastel (powdery chalk), which was never treated with a fixature in the 17th, 18th and 19th Centuries, will jump off the paper and adhere to the inside of the glass!

Damage caused by fly faeces

Damage caused by fly faeces

Some things you just must live with, such as houseflies whose poo can stain an oil painting and can only be removed with a scalpel (don’t try this yourself!). Thunderflies, in high summer, can find their way under the tightest-fitting glass and litter the surface of a watercolour or drawing. Wait until autumn and take the backing off the work on paper, dust them out and reseal.

An example of damage caused by silverfish

An example of damage caused by silverfish

Silverfish are a menace. If they get into a Victorian watercolour, they can munch their way through the pigments, which have been impregnated with gum Arabic, (the substance that Osama Bin Laden’s family fortune was based on), leaving patches of bald paper. Try to keep on top of silverfish by regular hoovering.

Another example of damage caused by silverfish

If you do have the misfortune to have water or fire damage or a painting falls off the wall, it makes sense to have a good photographic record of it, as this could help a conservator restore it and a loss adjuster assess a claim.
