Saturday Morning Western Pulp: Roaring Western Stories, May 1953
This is the only issue of this pulp known to exist, although there may be more. It's got an action-packed cover by Milton Luros, and the authors include Will C. Brown (really C.S. Boyles, the other famous author from Cross Plains, Texas), Bryce Walton, and several more, none of whom I've ever heard of. This was the era during which pulps were dying right and left, so the idea of starting a new one seems pretty risky, a risk that evidently didn't pay off. But considering that Westerns hung on longer than any other pulp genre, maybe it was worth taking. The issue looks like a decent one, anyway.
