A rare Ilya Mashkov still life painting entitled Still life with fruit has auctioned at Christie's London for £4.7m ($7.3m).
The oil on canvas, which hails from 1910, sold with an impressive 218% increase on its £1.5m top estimate.
Executed in the Russian, neo-primitivist style, the work led Christie's sale of Russian art by a considerable margin.
During the 1930s, Mashkov explained of the neo-primitivists: "We wanted our art to break though the existing, stagnant world of painting, to be powerful and full of rich colours.
"It was important for us that our artistic language sounded like an organ, an orchestra, a complex chorus, bringing society to a genuine understanding of art."
Last exhibited in 1913, the painting has remained in a private collection ever since. The present sale represents the first time it has come to market since its creation at the beginning of the 20th century.
The undoubted masterpiece by one of Russia's finest artists is, according to Christie's, "the most important example of Russian neo-primitivism to appear on the market in recent history".
Mashkov's Still life with flowers sold for £2.1m ($3.3m) at Sotheby's in December 2005, suggesting values for the artist's works are on the rise.
