Sergio Aragonés Groo the Wanderer #34

Sergio Aragonés brings his signature cartoony energy to this December 1987 Epic Comics entry, with cover art entirely his own — and it's a delight. The cover shows Groo grinning broadly alongside a white-bearded elder, the two surrounded by a pair of spotted hyena-like animals and a shaggy dog, while a mysterious glowing flask floats nearby — a cheeky tease for the interior story titled "The Amulet." A small inset panel in the corner hints at further chaos, and a tongue-in-cheek tagline ("The Fall of the Mutants Is Coming!") winks at Marvel's big crossover event of the year, reminding readers that Groo plays by nobody's rules but his own.
