This is Marvel Science Stories for November 1950, cover by Norman Saunders. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers, where the curators also include some interior art, including this piece by Frank R. Paul illustrating Lloyd Arthur Eschback’s “Overlord of Earth.”

And this rather dynamic illustration by Vincent Napoli illustrating A Bertram Chandler’s “Fire Brand!”
