Guardians of the Galaxy #37

The 31st-century Marvel Universe gets a genuinely unsettling twist in this June 1993 issue, as the cover — penciled by Kevin West and inked by Steve Montano — announces "Dr. Strange is Dead!" in bold, alarming fashion. Dominating the starfield backdrop is the massive, flame-crowned form of Dormammu, mystic energies crackling around him, while a colossal red-tentacled creature wraps itself across the foreground and two white-suited figures look on from the surface below. The cover's tagline — "Can even the 31st Century Sorcerer Supreme survive against the fatal fury of the Dread Dormammu?" — makes this an issue that fans of cosmic Marvel and mystical threats won't want to pass up.
