Doctor Strange #174

In "The Power and the Pendulum," Doctor Strange faces off against the formidable Lord Nekron, who has struck a dangerous pact with Supreme Satannish to secure eternal life—on the condition that he finds a willing mystic to take his place within a year. With time itself as his weapon, Strange pushes the limits of magic in a race against the clock, as Satannish watches from the shadows, eager to claim his prize. Written by Roy Thomas and illustrated with moody precision by Gene Colan, with inks by Tom Palmer and colors by the same, this 1968 Marvel classic features a cover by Colan and Palmer that captures the eerie tension of the spellbinding showdown.
