Off the top of my head...
Miller. Sin City aged like milk but the art was fabulous.
Azuma. Still producing one of the best comics ever made in Yotsuba&!
Buscema should get just as much credit for solidifying the visual side of Conan as Frazetta does.
Toriyama. Nothing to be said that hasn't been said a million times.
Sienkiewicz was one of the first in the 80s to turn comics into art.
Herge. Also nothing to say that hasn't been said a million times.
Hernandez has also produced one of the greatest comics of all time.
Inoue. Speaking of GOATed comics: Vagabond.
Simonson. If Thor was his only credit he'd still deserve his legendary status.
Loads more but I think the post is long enough.
