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 Serpentine's summer blockbuster is an exhibition of kitsch masterpieces from the American artist Jeff Koons. Michael Glover doesn't know whether to laugh or cry
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.
