Fritzi Ritz and Phil Fumble in Unpublished (?) story, 'Just Sup-Posing' page 4

This is the fourth page of the Fritzi Ritz story "Just Sup-Posing". I bought all four pages of this story, along with Jack Mendelsohn's "script" (in this gallery).

I'm not sure if this story was ever published. The "mostly finished" nature of the art makes me think it was not.

It states that this story was intended for a "Dec-Feb" issue, but there was no 1958/59 "Dec-Feb" issue of "Fritzi Ritz", as the title was cancelled after the previous issue.

If anyone has any information on this story (if and where it was published), please do let me know.

Almost certainly not by Ernie Bushmiller, I have added his name, as that is how it was sold. I'll replace it if and when the correct artist is identified.
