Action Comics #414

This July 1972 issue poses a genuinely unsettling question right on its cover: a man in civilian clothes tears open his shirt to reveal the Superman costume, while simultaneously an airborne Superman hoists a red car full of scrambling criminals over a city street — and the speech bubbles ask, "Hey, wait a minute! If that's Superman… who am I?" Nick Cardy's cover pencils and inks deliver that split-scene with real energy, police officers rushing in below as money scatters through the air. Along with the lead "Superman vs. Superstar!" story by Cary Bates with art by Curt Swan and inks by Murphy Anderson, the issue also features a backup starring the New Metamorpho — solid value at just 20 cents.
