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. While it is impossible to tell if the Moon Museum is actually on the moon without sending another mission to look, technicians have admitted to placing personal effects onto the Apollo landers, hidden in the layers of gold blankets that wrapped parts of the spacecraft which remained on the moon after the astronauts departed.
