Note: According to Bear Alley there are two different Whopper Space Stories, both a half of the 1955 title Space Story Omnibus: "I believe that a couple of years later the same stories and features were split into two volumes, both with the title Whopper Space Stories. There appears to be one original story, entitled "The Man in the Moon", added to the pair of volumes. Confusing matters even more, the first of these (with the T. E. North painting of a winged rocket approaching a space station) was also published in hardback with an additional frontispiece signed S.D.—almost certainly Serge Drigin."
