Astronaut autographs and autopens on space-related blocks, nine fully-used stockpages of space-related blocks or plate blocks (#C76, 1193, 1371, 1434-35, 1529), each signed by an astronaut; most are clearly autopens but the group does contain some genuine autographs, including Glenn, Carpenter, Lovell, Borman, Gibson and Garriott; the big question mark is a Neil Armstrong, which doesn't neatly fit as a recognized autopen and the felt-tip pen is difficult to read, but nonetheless it remains a stunning signature on a First Man on the Moon plate block along with matching blocks with Aldrin and Collins autopens; all stamps are Very Fine never hinged.
