Andres Serrano’s “Piss Christ” (1987) after it was attacked in April 2011 while on view at the Collection Lambert in Avignon, France. As confirmed by surveillance footage,  three vandals aided by “a hammer and an object like a screwdriver or pickaxe,” according to museum officials, attacked the piece, shattering glass and puncturing the print. No arrests were made; the work remained on view as it was, “so the public can appreciate for themselves the violence of the acts.”
