Superman #260

Superman #260 drops readers into a prehistoric-feeling clash, with Nick Cardy's cover depicting the Man of Steel reeling against a mysterious archer mounted atop a massive, winged eagle-like creature in mid-flight. The tagline promises "an action-packed adventure in a land where time stood still," perfectly setting the stage for the interior story "Keeper of the Eternal Flame!" A fine example of early-'70s DC adventure, with Elliot S! Maggin, Curt Swan, and Murphy Anderson bringing the story to life inside.
