First Edition (' Published by the Viking Press in October 1953'). This is a rare book and a rarer dust jacket. As you can see in the photos, the covers are exceptionally clean. The silver design on the front and the silver lettering on the spine are both very bright. The edges and corners are in very good shape. The page edges look very good. The covers have one imperfection: a 1/4 inch tear off the top edge of the spine. Nevertheless, I've rated the condition of the book Very Good Plus due to the otherwise excellent condition of the covers, and to the fantastic condition of the interior of the book. To begin, the book is very solidly bound from cover to cover with nicely tight pages throughout and no binding issues. Next, the pages all look terrific. They are exceptionally clean (I turned them all over and found a total of two small spots) and free of any wear. I didn't see any conspicuous creasing (there's one tip of a bottom corner crease). There are no markings. There are no attachments of any kind. And no one has written their name or anything else anywhere in the book. All of the illustrations (there are many in color) look terrific. The dust jacket is in very solid shape. I've rated it Very Good Minus Due to the small (1/2 by 1/4 inch) loss off the top edge of the spine, not reaching the lettering. The jacket is clean, with only the lightest amount of handling soiling. The red lettering on the front is very bright. On the spine it is a bit faded. There also a couple of instances of scuffing on the front. The flaps are in excellent condition. The jacket is NOT price-clipped, not clipped at all. It is protected by a fitted cover. From the back of the dust jacket: 'This magnificently exciting and informative book developed from the Collier's symposium tells you when men will make their first trip to the moon, what they will do when they get there, and how they will get back. Written by the foremost scientists in the field of astronautics, it is documented by facts, figures, and some of the most extraordinarily beautiful and detailed illustrations ever to appear in book form.'
