CB-65

CB-65 is a sketch of Mars four miles above, four miles up, and six miles above. The lines in the sketch seem to show spatial relations as well as a bit of the terrain or some planet or moon.

While it is unknown what painting of Chesley Bonestell's this may have eventually become, it could have been part of the very early planning of CB-21 (Twelve Miles Above Mars or Mariner VI Approaching Mars.)
