Maggie and Jigs were popular characters as I recall.
Before WW 2, and for all I know, still today, little pocket size porno comic books used to be sold with condoms. When I was 12, one of these got circulated among the 7th grade boys at my school. I still remember the profound shock I got from reading this thing. It was a crude parody of a popular daily comic strip; the first piece of porno I had ever seen. I can’t imagine how much greater the effect of current TV would be on similar age boys, although I suppose schools now give them more of an introduction than we got back then.
