Art can be provocative.
Artist's Shit (Italian: "Merda d'artista") is a 1961 artwork by the Italian artist Piero Manzoni. The work consists of 90 tin cans, filled with feces, each 30 grams and measuring 4.8x6.5cm, with a label in Italian, English, French, and German stating:
"Artist's Shit Contents 30 gr net Freshly preserved Produced and tinned in May 1961"
At the time the piece was created Manzoni was producing works that explored the relationship between art production and human production, Artist's Breath ("Fiato d'artista"), a series of balloons filled with Manzoni's breath, being an example. A tin was sold for €124,000 at Sotheby's on May 23 2007. [...]
One of Manzoni's friends, the artist Agostino Bonalumi, claimed that the tins are full not of feces but plaster; in contrast Manzoni's girlfriend Nanda Vigo, who helped him produce the cans, claimed the contents really were feces.
