We have here an enigma. Supposedly, we view an illustration drawn by Walter Popp in 1957 for a Beacon Press novel,'Trailer Tramp.' However. we view the knockover on a 1953 or 1954 novel cover published by Uni-Books entitled 'Country Club Cheat.' How can a knock-off predate the original? I do not know.
