Rudolph W. Zirm. Possibly the background was re-touched by a different artist or by Zirm himself. (I suspect Zirm re-touched it himself.) See: House Of The Mummy Men https://pulpcovers.com/house-of-the-mummy-men/ See my latest comment on that cover, which points out Zirm’s signature. Also see the following cover and my comment there (for signature identification): The Little Silver Corpses https://pulpcovers.com/the-little-silver-corpses/ Zirm did all three of these covers, which are variations on a single theme.
