This issue of SUPER SCIENCE STORIES has a good cover by Lawrence Sterne Stevens. Not one of my absolute best, maybe (in my opinion), but still eye-catching enough that I would have picked up this issue at the newsstand. And once it was in my hands, the lineup of authors inside would have been enough to get me to plunk down my hard-earned pazoors: Fredric Brown, Ray Bradbury, John D. MacDonald (twice, once as himself and once as John Wade Farrell), Murray Leinster, Frank Belknap Long, Margaret St. Clair, and Neil R. Jones with a Professor Jameson story. That's a lot of heavyweight talent.
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.
