Captain Marvel #16

A massive armored figure dominates this September 1969 cover, fist raised as a swirling explosion of flame and energy erupts behind it — and Captain Marvel himself, small but determined in his green-and-white uniform, charges toward the confrontation in the foreground. The cover teases "At Last: Face-to-Face with… the Intelligence Supreme!", promising the kind of cosmic showdown that made late-'60s Marvel such a thrill. Don Heck and Syd Shores deliver a striking contrast of scale and tension that makes it hard not to flip straight to the first page.
