Italian artist Piero Manzoni created 90 of these tin cans in 1961 that are ostensibly filled with the artist's feces. Some claim they are actually filled with plaster, however "an art dealer from the Gallery Blu in Milan claims to have detected a fecal odour emanating from a can." In 2008 one of the tins sold at a Sotheby's auction for £97,250 or approximately $153,625.
