Saturday Morning Western Pulp: Western Story, January 28, 1939
You run across "wanted poster" Western pulp covers like this from time to time. I suspect this one illustrates the lead novel, "Tombstone Justice" by Tom Roan. Other authors in this issue are Stuart Hardy, Jay Lucas, C.K. Shaw, Ray Humphreys, and Kenneth L. Sinclair. Not big names, but solid Western pulp authors.
