More to the point, it told art owners who arrived at Sotheby's in open fear that the millionaires' market in Impressionists was in free fall after the New York auctions last November that crisis might yet be averted. "It's not dead, there's a lot of life in this market yet," said Sotheby's chairman and auctioneer Henry Wyndham. The boost came from a sharp markdown of estimates from last autumn and from a weak pound, which attracted heavy bidding in euros and dollars.
