You too can own a bit of space history, but you'll have to be ready to pony up some cash. This gallery is a sampling of some of the space goods that have been auctioned at Swann Auction Galleries and Sotheby's. "Bravely to the Stars / No Obstacles for Heroism," is a color lithographic poster showing cosmonaut in red within red text forming the outline of a rocket ship, Moscow, 1968. Sold for $510.
