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 Paul Reinman, but his heads are much more wedge-shaped, and with eyes far apart and out of line. This is the same artist as on many Fran Frazer stories, with very narrow, pointed ears, and long hands and fingers. There is a possible, but unreadable signature on the head light of the train. Or perhaps just a railroad name.
