Jeff Koons bites back at 'copies' of balloon dog

How much is that doggy in the window? If it's a shiny sculpture by the artist Jeff Koons, then they start at $7,000 [£4,400]; if it's a plastic bookend produced by Toronto manufacturer Imm-Living and sold in a San Francisco art gallery you're looking at a mere $30 [£19]. And therein lies a snowballing legal dispute.

The Diary: Jeff Koons' curious world; BBC is young at arts; Jean

Jeff Koons gave British journalists a rare glimpse into his curious world a few days ago, after inviting them to his New York studio for a personal, guided tour. Referring to his 'Made In Heaven' series, the explicit set of works featuring himself with his former porn-star wife, Ilona, who went by the stage name of Cicciolina, he asked one of his many assistants sitting on computers to pull up a picture he wanted to show the group. "Could we see 'Ilona's asshole?' he said, matter-of-factly, as it emerged on a screen. "And that's me", he said, pointing to a healthy member behind her. He then went on to speak about the train that he is controversially erecting outside Los Angeles County Museum of Art, relating the movement of a train to the sexual act. He said the "woo-woo" noise represented a "plateau of orgasms", before sending the press on their way. I look forward to more of the same when he appears before the starchy British press at the Serpentine Gallery next week, to launch his latest show, Popeye.
