In the last days of More Fun Comics back in 1947, they debuted an odd bit of fun from Jack Mendelsohn and Howie Post (whose Sooper Hippie we've seen before) entitled Jimminy And The Magic Book:
Jimminy premiered in issue 121 of More Fun and had 16 adventures in the final 7 issues of the comic.
Besides the cover promotion on his first appearance, Jimminy got a pretty decent advertising push, with inside back cover adverts and house ads appearing in Action, Detective, Adventure and a host of others ranging from Buzzy to Animal Antics to Star Spangled Comics -
I'm sure you'd rather see the comics than the advertisements. I just wanted to note that it seemed like they thought they had something pretty good here, and it's easy to wonder how the series might have fared if introduced earlier, before the title was on the decline. Once they realized the book was going to stop, they started using three stories per issue, seemingly to make sure they were seen rather than lost to inventory.
From issue #121, here are the first two Jimminy and the Magic Book stories -
There were 14 more tales...
