That looks a little like a Norman Saunders cover to me, but it's not listed on his website, so I guess it's some artist whose work is similar. Whoever painted it, I like it. This pulp doesn't appear to have lasted very long, but this issue, at least, has some good authors in it: Cleve F. Adams, Edward Ronns (who was really the great paperbacker Edward S. Aarons), Norman A. Daniels (another prolific pulp and paperback author), Cyril Plunkett, and a couple of house-names.
