Sotheby's aims to raise as much as $35 million in New York in November for the owner of a Vincent van Gogh landscape painting that has hung in museums for the past six years. The blue-skied "The Fields (Wheat Fields)" was painted in France's Auvers-sur-Oise during the last weeks of the artist's life in the summer of 1890, according to a Sotheby's statement to be released on Monday. The unidentified owner loaned it to Amsterdam's Van Gogh Museum from 2001 until this year, when it went on show in Madrid, the auction house said. As art prices increase, museums are losing prized paintings. In the U.K., the Duke of Rutland may sell five Nicolas Poussin works that have hung in London's National Gallery since 2002, according to the Art Newspaper. The last Van Gogh landscape on the market fetched about $27 million in 1995, said David Norman, chairman of Sotheby's impressionist and modern art department, in an e-mail. "That was a very different market than today," Norman said. A Paul Cezanne still life that Sotheby's sold for $37 million last year fetched half as much in 2000, he said. Sotheby's and Christie's International, the two largest auction houses, are preparing for their November sales in New York, which last year raised about $1.5 billion. "The Fields" goes on show in Hong Kong and London next month before being offered in New York on Nov. 7.
