"Vampirella", by Warren Comics - hello Adolescence!
Both "Creepy" and "Eerie", by Warren Comics - Great collections of short, scary stories. Each was masterfully inked, and so unlike the DC, Marvel, Harvey comics.
I read a bunch of "Sargent Rock" and "Weird War". I later got into Heavy Metal and the work of Moebius and Jodorowsky's "The Incal". It was mind blowing.
