Tales to Astonish #55

From 1964, this Marvel gem puts Giant-Man front and center in a tense city-spanning standoff, his massive fists clenched as a swirling green energy trail — the telltale signature of the Human Top — cuts across the rooftops before him. The Wasp hovers in the background, and the cover copy raises the compelling question of how Giant-Man can possibly defeat a villain who can match him in size. Jack Kirby's pencils and Sol Brodsky's inks give the whole scene a kinetic, larger-than-life charge that perfectly suits Stan Lee and Dick Ayers's tale of two titans on a collision course.
