The prints, from a private collection, show NASA's groundbreaking astronauts in scenes in space and on the moon. Rare photos include what's purported to be the only clear photograph of Neil Armstrong on the moon from July 20, 1969, and photos taken by astronaut John Glenn, the first man to bring a camera into space. Perhaps most exciting is the first 'selfie' from space, taken in 1966 by Buzz Aldrin.
