[Clarksburg: Saucerian Publications, 1959].
Pamphlet. First edition. The Mitchell sisters recount their meetings with the "Space Brothers" and the information relayed to them to help save planet Earth. Judging from the terrific cover illustration it looks like they were maybe dating the Space Brothers since the two rather plain sisters are holding hands with the handsome and fashionably space-clad Space Brothers while their flying saucer is parked behind them in the woods. Worth if for the cover alone. Some sunning to edges of covers and minute puncture to front cover, else near fine.
