He is now one of the most sought-after artists. His work now commands millions of dollars in the auction houses of Britain and America. In February 2005 Jewish artist, Lennie Lee, was censored for exhibiting a piece called "Judensau" (Jew pig) in Treptow Town Hall gallery, Berlin. The intervention was organized by the other artists working in the show who claimed (incorrectly) Lee was one of them. Lee's work was designed to put the institution in a difficult position. If they left it on the wall they would be accused of anti-semitism by their opponents. On the other hand, if they took the work down, they would be censoring the work of a Jewish artist dealing with antisemitic stereotypes. The authorities were forced to take the piece down. The piece attracted considerable attention from the media. Lee offered to remove his "Judensau" on condition that a 14th-century sculpture of a "Judensau" was removed from the side of Martin Luther's church in Wittenberg. On January 4, 2006, while on display in the Dada show in the Pompidou Centre in Paris, Marcel Duchamp's "Fountain" was attacked with a hammer by Pierre Pinoncelli, a 77-year-old French performance artist, causing a slight chip. Pinoncelli, who was arrested, said the attack was a work of performance art that Marcel Duchamp himself would have appreciated. This may be true, as on one occasion visitors to a Dada show were invited to smash up the exhibits with an axe. Previously in 1993, Pinoncelli urinated into the piece while it was on display in Nîmes, in southern France. Both of Pinoncelli's performances derive from neo-Dadaists' and Viennese Actionists' intervention or manoeuvre. The "Fountain" attacked by Pinoncelli was actually number 5 of 8 recreated by Duchamp at a much later date, after the original one was lost. Another is on display in the Indiana University Art Museum, and there is one also in Tate Modern, where in 2000 it too was the target of a urination performance (unsuccessful according to the gallery) by Yuan Chai and Jian Jun Xi. Artist Cartrain removed a packet of Faber Castell 1990 Mongol 482 series pencils from Damien Hirst's installation at his restaurant Pharmacy. This followed Hirst's action against Cartrain for using copies of Hirst's work.
