$18,000 Bar Of Soap

Perhaps the oddest piece of work at Art Basel is a bar of soap, displayed on a square of black velvet, purportedly made from Italian Prime Minister Silvio Berlusconi's fat, removed during liposuction.

Gianni Monti's work called 'Clean Hands' -- the title is a play on the name of an anti-Mafia group -- sold in less than an hour for 15,000 euros ($18,000) to a private Swiss collector, according to Monti's Galerie Nicola von Senger of Zurich.
