I had a dig through many of my old kids books recently when visiting home. Among the many I had forgotten all about was 'Willy the Champ' which follows a small, nerdy chimpanzee who gets bullied a lot by big, butch gorillas until he loses his shit and accidentally knocks one of them out. Despite having a really lurid visual style anyway, there is an awful lot of hugely homo erotic imagery going on which is, of course, great.
Some small scans here on this blog which moans about it being an inappropriate display of violence for wee kids (I will have been reading this as a kid during the early 90s, how things have changed even now I guess?!) but you will get the idea. I'd certainly recommend having a proper look in person if anyone gets the chance:
