NEW YORK, N.Y.- On 23rd September Sotheby’s New York will present The Collection of Allan Stone Volume III. The sale of property from the renowned New York dealer follows two exceptionally successful auctions in May 2011. Just as in those sales, this offering is made up of outstanding examples by the key artists represented and collected by Mr. Stone; highlights include works by Willem de Kooning, John Chamberlain, Franz Kline, Joseph Cornell and, perhaps most importantly, Wayne Thiebaud. Trained as a lawyer, but passionate about art, Mr. Allan Stone opened his own gallery in 1960. He joined the ranks of influential New York dealers such as Leo Castelli and Sidney Janis, while blazing his own path with a unique selection of artists.
