In November, 1969, the New York Times reported on the existence of a secret, miniature art museum that had been smuggled onto the surface of the moon on Apollo 12:
…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.According to the Times, the artworks are, clockwise from the top center: Rauschenberg’s wavy line; Novros’ black square bisected by thin white lines [in 1969, Novros also created the incredibly rich, minimalist fresco on the second floor of Judd’s 101 Spring St]; a computer-generated drawing by Myers; a geometric mouse by Oldenburg, “the subject of a sculpture in his current show at the Museum of Modern Art” [a sculpture which is in MoMA’s permanent collection, btw]; and a template pattern by Chamberlain, “similar to one he used to produce paintings done with automobile lacquer.” Warhol’s contribution, which is obscured by the thumb above, is described as “a calligraphic squiggle made up of the initials of his signature.”
