Power Man #17

Luke Cage bursts through a crumbling wall on this 1974 cover, bullets sparking harmlessly off his steel-hard skin as a ring of gun barrels closes in — a vivid demonstration of why the cover itself bills him as "The First and Still the Greatest Black Superhero of All!" The promise of Iron Man guest-starring adds another layer of excitement, teasing an unlikely collision between Cage's street-level toughness and the armored might of one of Marvel's biggest names. Gil Kane's pencils and Billy Graham's inks give the scene real kinetic energy, making this a genuinely striking entry in the early Power Man run.
