Sergio Aragonés Groo the Wanderer #39

Sergio Aragonés pulls off a wonderfully self-referential trick on this cover, depicting a grinning, goggle-eyed dog bursting right through the comic's own interior panels — scattering Groo and his trademark chaos across a grid of scenes packed with battling warriors, bewildered bystanders, and sword-swinging mayhem. The story title "A Groo's Best Friend" hints that our hapless wanderer's relationship with this very canine is central to the fun, and Aragonés's rubbery, expressive linework (he handles both pencils and inks here) makes every corner of the cover overflow with comic energy. A charming 1988 entry from Epic Comics that showcases exactly why this series earned such devoted fans.
