Some are wondering whether the art market has peaked after a weak night at auction last night:

High-profile impressionist paintings failed to sell at auction at Sotheby's in New York prompting fears that art's dizzy boom could be nearing an end.

Works by Vincent Van Gogh, Pablo Picasso and Pierre-Auguste Renoir went unsold at Sotheby's sale of Impressionist and modern art last night although the sale of less expensive works resulted in £128.8 million of art going under the hammer.

The total was much less than the auction's low pre-sale estimate of £170 million and far less than the £235 million top estimate.

Van Gogh's The Fields (Wheat Fields), thought to be the last landscape ever painted by the Dutch artist, was expected to fetch in excess of £20 million. But the 1890 work received no bids. . . .

Four paintings by Picasso, including his landmark 1931 masterpiece La Lampe that came onto the market directly from the artist's family, failed to sell. Typifying the uncertainty, works by Renoir, Matisse, Monet and Chagall all went under the hammer last night while other paintings by the artists remained unsold. Twenty out of the 76 lots failed to find a buyer. . . .

"The Van Gogh painting not selling is a huge shock," said one European art dealer speaking on conditions of anonymity.

"This gives more indication that the art boom is on course to be another casualty of the global economic downturn in which case maybe we should all go and do something else for a few years."
