The Spectacular Spider-Man #9

Against a backdrop of fire and a crowd of protesters raising signs reading "No Retreat," "Action! Not Talk!," and "Fight Back!," the White Tiger leaps forward in his striking all-white costume — billed right on the cover as Marvel's most controversial creation making his color-comic entrance. Spider-Man scrambles behind him amid the flames as the tagline "The Flames of Protest!" sets a charged, socially conscious tone rare for 1977 superhero fare. George Pérez pencils and Frank Giacoia inks deliver a cover that crackles with energy and genuine stakes, making this one hard to pass over on the spinner rack.
