Superman's Pal, Jimmy Olsen #149

The cover of this 1972 DC gem puts Superman in a startling spot — a red-haired, green-jacketed Jimmy Olsen yanks at the Man of Steel's cape on a busy city street, jabbing an accusatory finger and declaring, "This proves you're the killer — Superman!" The shocked expression on Superman's face and the alarmed onlookers in the background make for a genuinely gripping tableau, all rendered with crisp energy by cover artist Bob Oksner. And as a bonus, this 52-page issue also promises "the sensational exploits of the one and only Plastic Man," teased in a flashy corner banner — plenty of adventure packed into one quarter.
