JEFF KOONS
Jeff Koons (born January 21, 1955) is noted for his use of kitsch imagery, sometimes in sculptural form and extremely large in size. Koons' early work was in the form of conceptual sculpture, one of the best-known being Three Ball 50/50 Tank, 1985, consisting of three basket balls floating in water, which half-fills a glass tank. Koons then moved on to "Statuary", the large stainless-steel blowups of toys, and then a series "Banality", which culminated in 1988 with Michael Jackson and Bubbles -a life-size gold-leaf plated statue of the sitting singer cuddling Bubbles, his pet chimpanzee. Three years later it sold at Sotheby's New York as Lot 7655 for $5,600,000, trebling Koons' previous sale record.
