LONDON.- A previously unknown painting by Walter Sickert, entitled The Blind Sea Captain, is one of the highlights of the 20th Century British Art Sale in New Bond Street on the 9th March. The painting, which is estimated to sell for £40,000 – 60,000, is from a private collection, inherited by the vendor from her grandfather. The art historian Wendy Baron, who has devoted her life to studying the works of Walter Sickert, was astounded to find a painting by the artist that she had never seen. Sickert is considered a prominent figure in the transition from Impressionism to modernism, and an important influence on distinctively British styles of avant-garde art in the 20th century. Notorious for his paintings of nudes, four of them controversially entitled, The Camden Town Murder, after a well publicised and gruesome murder of a prostitute in 1907, certainly gained Sickert attention and he became a prominent member of the Camden Town Group of artists.
