Outstanding official NASA photograph signed by three members of Flight 41B, Challenger's 4th mission. This vibrant color 10 x 8-inch photo features all five flight members -- Robert L. Stewart, Ronald McNair, Bruce McCandless II, Vance D. Brand, and Robert L. Gibson -- with McCandless and Stewart in full flight gear. Includes Brand ("V. Brand") and Gibson's ("Robert L. Gibson") signature as well as McNair's, the first African-American astronaut, who later died when Challenger exploded on its 10th mission. The NASA logo and crew member listings appear on the back. No place, no date, circa 1984. Near fine.
