Superman #331

Superman #331 opens with a striking cover by Ross Andru and Dick Giordano that splits the action across two panels: a straining Man of Steel pounds uselessly against an energy-crackling barrier on the left, while the armored Master Jailer looms on the right, clutching a helpless Lana Lang as bystanders look on. The cover's taunting caption — "When the Master Jailer builds a cell, not even YOU can break out!" — sets up a genuinely tense scenario for the story "Lockup at 20,000 Feet!" This 1979 DC issue promises high-stakes peril with a villain confident enough to use Lana as leverage, making it a compelling chapter in Superman's Bronze Age adventures.
