I would readily concede that the art is simpler now (and Fritzi isn’t exactly the same “hot tomato” she once was depicted as), but I would also say the specific strip I posted isn’t representative of the art in the modern strip. Usually characters are facing the viewer, and there’s a bit more variety in panel construction. And I can’t speak for Bushmiller, but from what I’ve heard about the fella he loved a good gag and ahem cashing checks – so I’d like to think even if he didn’t think its modern form was funny, he’d be pleased that Nancy was still a going concern. But that’s just my two cents as a fan; I’m neither a historian or psychic.
