A Scottish painting dubbed Apple Green will be auctioned at Bonhams' annual Scottish Sale
The artwork, dubbed Apple Green by Scots artist Stanley Cursiter, hasn't been seen in public since 1929.
The painting is 40×50 inches and has been in the same family since it was bought for just £300.
But it is one of the leading lots at Bonhams' annual Scottish Sale in Edinburgh on April 26 – and is estimated at between £100,000 and £150,000.
Painted in 1925, Apple Green was exhibited at the Royal Academy in London in the same year, at the Royal Glasgow Institute in 1926, and at the Royal Scottish Academy in Edinburgh in 1929 – the last time it was exhibited to the public.
Cursiter played a major role in Scottish art for much of the 20th century.
The painting 'Twilight' by Stanley Cursiter
Born in Orkney in 1887, he studied at Edinburgh College of Art and was one of the first artists to introduce Post-Modernism and Futurism to Scotland.
Stanley Cursiter's series of interiors are among his finest achievements
He adopted the more realist style seen in Apple Green after World War I and also expressed an interest in interiors through his paintings.
Bonhams Head of Scottish Painting, Chris Brickley, said: "Stanley Cursiter's series of interiors are among his finest achievements, and this rediscovered picture is one of his most significant exhibition pieces."
