Some instant nostalgia for children of the space age, courtesy of the Dreams of Space site which chronicles and exhibits some of the cool space art found in children's books from 1883-1974. A majority of the stuff dates from the 60s, when the fantasy of space flight was becoming reality, and the possibilities appeared limitless. The illustrations from the early 60s are interesting in that the artists weren't yet constrained by NASA's own project blueprints and were able to let imagination take over. In the late 60s and early 70s, the art was based on actual NASA plans, although still heavily optimistic.
