Edmond Hamilton / Harl Vincent
In the tradition of the old 'Ace Doubles' two-in-one books (flip one over to read the second title) -- here is the first Wildside Double . . . 'The Sargasso of Space and Two Others,' by Edmond Hamilton and 'The Copper-Clad World,' by Harl Vincent. Two oldtime science fiction authors at their galaxy-spanning best! 3
