I have a "Showcase" collection of 50s (at least I think they are from the 50s) Superman comics that I've been reading lately. I guess as a result of the Comics Code almost all of these comics are about Superman obsessively protecting his secret identity and avoiding marriage rather than doing something more interesting like fighting villains.
One of the things I wasn't aware of before reading these is how often the artists would use the same pose of Superman not only in multiple issues but frequently within the same issue... It's clearly a case of having a drawing and slapping it on a light box and using the same drawing over and over again. It's a little depressing, but I understand the reasons for it... those guys had tight deadlines and probably didn't get paid a lot. There is one artist who only pops up occasionally in the book who's clearly head and shoulders above the other artist(s?) contained in the book... the inks are more polished, the characters less stiff and more emotive and the general treatment is more fun. No idea who it is.
