Sunday Morning Bonus Pulp: Science Fiction Quarterly, February 1957
Ed Emshwiller is one of the classic science fiction cover artists, and this is a pretty good one. This issue of SCIENCE FICTION QUARTERLY has a good line-up of well-regarded authors inside, too: Frederik Pohl, Philip K. Dick, Wallace West, Randall Garrett, and Margaret St. Clair. I don't know anything about D.A. Jourdan, who wrote the other story featured on the cover.
