The back of this zippered Flash Gordon wallet features a blue rocket ship flying between two ringed planets as explosions burst around it.
Collector Michael O'Harro gave this wallet to the Smithsonian in 1993 as a part of a large donation of space science fiction objects.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
