Of the three people on this cover, I think the girl is the scariest of the bunch. This gun-toting redhead with the oddly intense eyes shows up on a number of Western pulp covers painted by Tom Lovell in the mid-Thirties. She must've been a model he used. I wouldn't want to get on her bad side, like whoever it is this trio is facing off against.
I wasn't familiar with Oliver King, who wrote the lead story in this issue, so I looked him up and discovered that he was really Thomas Ernest Mount, who was best known under the pseudonym Stone Cody. I've read some of his work under that name and enjoyed it. The other authors in the lineup -- Walt Coburn, Harry Olmsted, Cliff Farrell, James P. Olsen, among others -- are good ones as well.
