Of course, Fosdick was a takeoff of Dick Tracy. Imagine that, a strip that made fun of another strip! Capp even made fun of Chester Gould by creating a cartoonist character who was always being fired from the syndicate, named Lester Gooch.
Somebody who knew Gould is supposed to have said that Gould had had enough of Fostick. "Enough is enough!", he was supposed to have said. Someone else quoted Gould as saying that he loved Fostick because everytime Capp did a Fostick strip a couple more papers would pick up Dick Tracy.
Fostick was immensely popular in its day. If anybody ever complained about the violence it never reached my kid ears.
Fostick was a goldmine for Wildroot Cream-Oil. When I was a kid I used to use Wildroot just because Fostick used it. You trusted Fostick. If he said a product was OK that was all the argument that you needed.
Just for the heck of it, here's a picture Capp drew of himself. And, by the way, the sample pages above are taken from three different stories. If you couldn't figure out what the story was, that's why.
