World's Finest Comics #302

In "The Superman-Batman Split!", a dying man named Ronald Jason uses a mysterious radioactive element to impersonate two alien invaders, pitting Superman and Batman against each other in a high-stakes deception. Written by Cary Bates and illustrated with striking detail by Neal Adams, with inks by Dick Giordano and lettering by Ray Holloway, this 1984 classic features a tense, cleverly constructed conflict where trust is the real casualty. The cover by Ed Hannigan and Klaus Janson captures the dramatic split between the two heroes in bold, dynamic style.
