Superman #140

Superman stands restrained — his wrists locked in mechanical shackles — before the sweeping grandeur of Kandor's Royal Hall of Justice, a breathtaking Kryptonian chamber of towering violet columns and glowing amber lights. Rows of armored robot soldiers line the hall as a hulking mechanized guard looms at his side, the distant tribunal platform suggesting the Man of Steel is about to face some form of judgment within the bottled city. Paul Rivoche's cover captures a genuinely compelling image of Superman stripped of his freedom but not his composure, making this December 1998 installment of Ron Marz's four-part "City of the Future" arc one you'll want to track down.
