Space Shuttle Challenger crew-signed photo, depicting the seven crew-members from the STS-51-L mission. Challenger was to be the twenty-fifth flight of the American Space Shuttle program, which marked the first time an ordinary civilian, schoolteacher Christa McAuliffe, had flown aboard the Space Shuttle. Signed by all next to their respective images: ''El Onizuka'', ''S. Christa McAuliffe'', ''Greg Jarvis'', ''Judy Resnick'', ''Mike Smith'', ''Dick Scobee'' and ''Ron McNair''. Signed by all in black felt-tip except Jarvis, whose signature has faded. Half-matte photograph measures 10'' x 8'', framed with the mission patch to a size of 17.75'' x 10.875''. Not examined out of frame and likely mounted to mat, overall very good plus condition.
