I think the questionable costuming choices in this "Exciting Comics" cover from 1940 pretty much speak for themselves, but you have to credit the guy in purple for remembering to include a reservoir tip:
And I'm not sure whose pleasure that robot is ribbed for, but no matter what I'm glad to see that even in 1940 they put safety first. You can have your Y2K era leather-clad Bat-heroes; for my money, latex is always your best bet.
I think it’s interesting that the latex villain is sporting a reservoir tip. Very safety conscious of him.
I find it interesting that our latex-clad friend is covered head-go-toe with one exception: his hands. Come on man! Haven’t you heard? No glove, no love!
I find it especially safe to wear tanning sunglasses everyday to protect your eyes from UV-rays (or ray guns). Much like the martians here are sporting. However, I dont know that it’s completely necessary to have them shaped like certain parts of the female anatomy… but, whatever floats your boat.
