I once saw this in an antique/junk shop when I was a kid, and I could kick myself for not getting it. About a dozen years ago, however, I finally found this issue in a different antique joint, and then last night I finally scanned the appropriate parts of the giant thing.
As always, Chesley Bonestell is beautifully evocative, and Fred Freeman is king of the cutaways.
Enjoy,
