The Amazing Spider-Man #77

From October 1969, this chapter of Marvel's flagship title promises high-stakes action right in its title — "In the Blaze of Battle!" John Romita's cover delivers exactly that, depicting a flaming, red-hued Human Torch hurling himself in a blazing arc toward Spider-Man, while a green-scaled, reptilian figure — the Lizard — looms menacingly in the foreground. Three such wildly different combatants sharing one cover makes for a genuinely compelling visual, and with Stan Lee and John Buscema handling the story inside, the excitement is more than just cover-deep.
