Superman #174

High above a busy city skyline, Superman hovers confidently while a bespectacled, cape-less Clark Kent tumbles in freefall beside him — the cover's speech bubbles teasing a fascinating identity crisis at the heart of "Clark Kent's Incredible Delusion!" Curt Swan's pencils and George Klein's inks give the scene a crisp, dynamic energy that perfectly captures the disorienting drama of a man questioning his own reality thousands of feet in the air. With Edmond Hamilton scripting, this January 1965 issue promises a genuinely clever twist on the Superman mythos that fans of the era would have snatched right off the spinner rack.
