Superman #22/1972

In "Supermans Festung verkauft," Superman faces a chilling threat when Rose is struck by a car and taken to a hospital—only to fall into the clutches of a deranged doctor obsessed with transforming humans into protoplasm. With Cary Bates scripting and Don Heck handling both art and inks, the story unfolds with tense urgency, as the hero races to stop a madman’s twisted experiment. Nick Cardy’s cover captures the moment’s dread, perfectly framing the danger lurking within the medical facility.
