Unlike Doug Rosa, much is known about Mort Kunstler. His career as a historical painter made his name. Kunstler painted only a single Doc Savage cover for Bantam — Brand of the Werewolf. He can boast that novel sold the most copies of any single Bantam Doc Savage paperback.
Hidalgo Trading Company writer, Ron Hill, wrote that Kunstler’s cover was “too cartoon like.”
Kunstler’s official website does present his Doc Savage cover. The scan, however, isn’t from the original art. It’s obviously a worn and bent copy of the paperback.
