Adam Lindemann regales Sarah Douglas, Editor-in-Chief of ARTnews, with his stories and adventures on the art auction market. Lindemann explains the strategies he uses to approach estimates, reserves, guarantees and private sales. One of the most successful sellers at auction, Lindemann set the record price for a living artist in 2007 when he sold Jeff Koons's Hanging Heart for $23m. He succeeded again when his Jean-Michel Basquiat painting sold for a record price of $57m.
