These metal earflaps came from a leather Buck Rogers helmet from the 1930s. The wearer could act out Buck's space adventures - and imagine new ones.
Michael O'Harro gave these toy parts to the Museum in 1993 as a part of a large collection 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.
