Superman's Pal, Jimmy Olsen #137

Superman charges forward with fists clenched as a massive, shadowy four-armed creature looms over the cracked, rocky landscape behind him — it's a striking image of raw menace brought to life by Jack Kirby's pencils and Neal Adams' inks. Scrambling alongside the Man of Steel are the Newsboy Legion and the shield-bearing Guardian, their faces etched with alarm as the cover promises "the last day of the world." Kirby's 1971 run on this title was delivering ensemble adventure at full throttle, and this issue — with its apocalyptic stakes and crowd of colorful characters — shows exactly why.
