black and white comics of the 90s. stuff like Scud the Disposable Assassin, La Cosa Nostroid, Stray Bullets, Love and Rockets, Why I hate Saturn, Torso, From Hell, Black Hole, GEARS, Maus. Some of these would be considered NSFW. most not because of the gore/violence but subject matter and mature stories.

Indie comics of the 90s was pretty much the peak of this stuff. OR for something more familiar the original run of TMNT comics from the 80s.
