There used to be a comic book called Treasure Chest of Fun and Fact, published by George Pflaum and distributed through Catholic elementary schools. Most of its content was kid adventure and biographies of incredibly unhip historical figures (John Philip Sousa and Eamon deValera are the two I remember). It wasn’t an attempt to scare anybody, and given its limited distribution system, I doubt many Jewish or Protestant kids ever even saw it.
I’ve never seen, for example, a Hasidic “Don’t work on Sabbath or G-d will Smite You” mini-comic. I have seen some Hare Krishna tracts, but didn’t examine them very closely.
