The 20th century portraitist Meredith Frampton (1894-1984) achieved remarkable success in a relatively short career.
Despite his limited output, which was hampered by failing eyesight, his pictures hang in the National Portrait Gallery, the Tate and Imperial War Museum. His work rarely makes it to auction: just 14 results are listed on the Blouin Art Sales Index.
So when his pictures do come on the secondary market they tend to cause a stir. In 2010, Bonhams set a new auction record for the artist when it sold a portrait of the distinguished palaeontologist Clive Forster-Cooper for £66,000.
