Another re-scanning project book. The "adventure in Space" books with Willy Ley and John Polgreen are some of the best space art books from the 1950s. So this is a chance to show you some "better" scans of this beautiful art. I really don't have much to add except that copios of these books are widly available and worth finding.
Here are some links to other blog postings about these books:
