Moon Museum is a small ceramic wafer three-quarters of an inch by half an inch in size, containing artworks by six prominent artists from the late 1960s. The artists with works in the "museum" are Robert Rauschenberg, David Novros, John Chamberlain, Claes Oldenburg, Forrest Myers, and Andy Warhol.This wafer was supposedly covertly attached to a leg of the Intrepid landing module, and subsequently left on the moon during Apollo 12. The moon museum is considered the first Space Art object.
