Andy Warhol, Sticky Fingers: The Rolling Stones, 1972

Prints, Lithograph, offset, with metal zipper on album. Size: height - 12.2 in, width - 12.2 in, depth - 0 in. signed, in black marker. Estimate: from $2,500 to $3,500

Note: Most outrageous of all the Rolling Stones albums, signed by Warhol with his infamous photograph of a crotch shot and a real metal zipper. At first, several department store chains refused to display the album because of the model's rather snug jeans. "If you stand back from that cover," says album designer Craig Braun, "you can actually see the guy's dick. I used to kid Andy: 'I know you had that guy playing with his dick before you shot the picture!'"
