Damien Hirst's latest formaldehyde masterpiece "The Golden Calf" and his announcement to auction off a collection of previously unseen work later this summer are currently causing quite a stir in the contemporary art market. This is the first time a living artist has ever put a collection of brand new work straight out into the open market. The Golden Calf is crowned by a solid gold disc, it's hooves and horns are cast in 18K gold, and is encased in a 24 K gold box which sits on a solid marble base. This is Hirst's largest ever formaldehyde work and is expected to sell for around $24 million. Sotheby's will be conducting the 10 day pre-sale exhibition and 2 day sale sometime in September.
