Late 80s and 90s Dc is one of my favorite era of books. Spectre, Hawkworld, JLA, Starman, Sandman Mystery Theatre, Waid's Flash, David's Aquaman, Grell's Green Arrow, Hitman and quite a lot more. And I'm not even mentioning Vertigo (90's Vertigo is probably one of the best era a publisher ever had quality-wise)
