Originally credited to Irv Novick, but the movement of the figures are too stiff and awkward, and none of his faces are found here. Notice inking, the narrow pointed ears and long hands and fingers, which can be found in some other stories in Fran Frazer and Zambini, Zip Comics #23.
Originally credited to Bernard Klein, but this has none of his small heads with angry eyebrows in sideview. It is identical to King's signed stories in #19.
