Outer Space #20

This issue contains two stories. "The Duplicos" depicts an encounter with alien duplicates whose repulsive appearance and frightening nature lead a president to order their destruction, despite one character's moral objection to killing living beings. "The Folding Chair" tells of a young inventor named Peter who creates a revolutionary folding chair after struggling with a malfunctioning one on vacation; when Professor Haines develops high-powered transistors and tubes, he builds his own hearing device based on Peter's folding chair design, discovers it can amplify distant sounds like bird songs, and happily returns to his regular work.
