Wednesday Cover" the 1953 Fiction House sci-fi one-shot, Man O' Mars. Well, that comic, featuring the heroic John Hunter of the Marsmen, has been reprinted a couple of times, including this edition from a shady outfit known as I.W. Publishing in 1958. The Grand Comics Database tentatively credits the art to Sid Check.
Whoever actually drew it, it's a terrific pulp space opera tableau, with all the elements - flying saucers, bubble helmets, rayguns, etc. - that make the genre such a personal favorite.
