My top recommendation of the moment is a dive into Gay Comix / Gay Comics (not to be confused with early Archie strips) which ran from 1980-1998. To my knowledge, there's not a full reprint but you will be able to find copies online. (I'm linking to a web post on the publication.) Unlike any other print archives I've gone through, Gay Comix is a wide survey of gay/lesbian attitudes through the peak of the AIDS epidemic and the rise and fall of various subcultures. It's fascinating, inspiring, and often quite funny. I particularly love whenever Jennifer Camper shows up.
