A high percentage of western paperback covers are unintentionally absurd, and this one by an unknown artist for the obscure 1959 novel Sierra Slayer fits the bill. This was written by Anthony G. Murphy, and he had us baffled for a while. Then we disscovered he was actually a Spanish writer named Antonino González Morales, who was both a journalist and novelist, using multiple pseudonyms, including Ambler Ketchum, Ana María Luján, A. G. Morales, A. G. Murphy, Alex Mor, Inglis Carter, Gordon C. McGuire, and possibly others. The name Anthony G. Murphy was generally reserved for his westerns, and Sierra Slayer, which was put out by George Turton Publishers in Britain, would, then, have to be a translation from Spanish. All of which brings us back to the art. Since Turton was not a major publisher, it possibly reused the Spanish art, and since Morales/Murphy wrote his westerns for Madrid's Editorial Rollán, and many of those were illustrated by Prieto Muriana, this could be Muriana's work. Then again, it easily could not.
