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.
