Cashing in on the space race and impending moon landings, Mattel brought out the first Major Matt Mason figure in 1966. In 1970, a boy can get fellow astronauts Sgt. Storm, Lt. Jeff Long and Doug Davis (a civilian), as well as a 3-level Moon Base, Lunar Crawler vehicle and several aliens...including Callisto (who hails from Jupiter). All of these are on sale at McCrory's.
