Marina Abramovic, Wim Delvoye, Kimsooja, Nanda Vigo and others on Piero Manzoni

Conceptual artist Piero Manzoni, an enfant terrible of Italian art in the 1950s and early 1960s, is best known for Artist's Shit (Merda d'artista) (1961), 90 sealed cans priced by their weight in gold, one of many works that question the nature of the art object. Other stunts included balloons filled with "artist's breath" and “Living Sculptures,” human subjects signed by Manzoni.
