Hi Jimmm,
I'm sure the depiction of girls in their undergarments would have been appreciated by a male teenage audience, much as Betty and Veronica were, but it was all done innocently enough by those involved, and was under the radar of most teenage boys that might be persuaded to spend 12 cents on these comics. As I noted, its likely some boys did take notice of them in their sisters or cousins collections, but many of us didn't have a clue that the images in those comics were of a more purient bent than those that appeared in our super hero, mystery, war or western fare.
