A nice British paperback of The Secret Galactics, a novel by A. E. Van Vogt. In my opinion, this is the nicest looking edition it has had. This orginally came out in 1974 in a trade paperback from Reward Books - who used a poorly drawn cover that would scare away most readers of serious SF. British publishers kept this title in hardcover and paperback, but the American mass-market paperback from DAW Books changed the title to Earth Factor X. While this cover is in the Chris Foss style (he was the most sought-after British SF cover artist of the Seventies) - I'm sure it was done by someone else, who was told to "make it look like Foss." (Perhaps Eddie Jones?)
