I usually think of Walter Popp as a paperback cover artist, but he did some pulp covers, too, including this one for THRILLING WONDER STORIES. Inside are stories by Murray Leinster, Chad Oliver (always nice to see a pulp with a story in it by someone I've actually met), Kris Neville, Wallace West, John Christopher, and a couple of lesser-known authors, R.J. McGregor and J.W. Groves. If you'd like to read this issue, it's available on the Luminist League website here.
I'm not sure what's going on in this cover by Howard V. Brown, but that looks like a mosh pit in the background. Well, they do say that science fiction can predict the future. Inside this issue of ASTOUNDING STORIES are stories by some great writers: Jack Williamson, Murray Leinster, Stanley G. Weinbaum, Nat Schachner, Raymond Z. Gallun, Ralph Milne Farley, and Wallace West. F. Orlin Tremaine was still the editor at this point, but John W. Campbell has an article in this issue. The whole issue is on-line at the Internet Archive, so I guess if I'm curious enough about that cover, I can find out.
I don't know about you, but I find that cover by Howard V. Brown intriguing. Scans of this issue are available on-line. I may have to see if I can find time to read it. The line-up of authors is certainly a strong one: Murray Leinster, Jack Williamson, Arthur J. Burks, Harl Vincent, Wallace West, Robert H. Leitfred, Desmond Hall (writing as Ainslee Jenkins), and a couple of lesser-known authors, Stuart Jackson and Holloway Horn. You can find a PDF of this issue here.
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.
All that futuristic-looking machinery in the background, and the girl's using a plain old revolver. But hey, it's Earle Bergey's work, so I'm not going to complain. I wouldn't complain about the contents of this issue of THRILLING WONDER STORIES, either, since it features stories by Arthur C. Clarke, Henry Kuttner, Jack Vance, L. Ron Hubbard, Walt Sheldon, and Wallace West. That's a pretty good lineup.
