Did you know that there's a teensy museum on the moon?
Now I find out there was already an entire Moon Museum, with drawings by six leading contemporary artists of the day: Andy Warhol, Robert Rauschenberg, David Novros, Forrest "Frosty" Myers, Claes Oldenburg, and John Chamberlain. The Moon Museum was supposedly installed on the moon in 1969 as part of the Apollo 12 mission.
I say supposedly, because NASA has no official record of it; according to Frosty Myers, the artist who initiated the project, the Moon Museum was secretly installed on a hatch on a leg of the Intrepid landing module with the help of an unnamed engineer at the Grumman Corporation after attempts to move the project forward through NASA's official channels were unsuccessful.
