Namor, the Sub-Mariner #21

Part of Marvel's "Search for Iron Fist" arc, this December 1991 issue takes Namor's world far from the ocean and into the mountains, as the cover — drawn entirely by John Byrne — sets a striking scene: a group of figures stands on a high ledge overlooking the dark, spired cityscape of K'un-L'un, with a blonde figure leaping or falling dramatically in the foreground against snow-capped peaks and a blazing sun. Namor himself watches from the corner inset, lending the familiar face of Marvel's Sub-Mariner to what promises to be an adventure steeped in mystery and exotic locale. Glynis Oliver's colors give the cold mountain setting a vivid, otherworldly quality that makes this an eye-catching entry in the series.
