Adventures into the Unknown #51

This issue features "Adventures Into The Unknown" with a Truevision 3D format (requiring special glasses). The cover story depicts a skeletal, caped villain menacing a woman in a supernatural setting. The editor's letter announces the magazine's pioneering use of the new Truevision 3D technique for comics and promises supernatural thrillers including "Nightmare," "The House That Was," "Death Mask," and "The Monster." One story visible in the sample pages involves a scientist named Ralph and his companion discussing a protoplasmic creature or life form that has developed intelligence and acquired a brain, with dialogue suggesting conflict between the characters over a dangerous experiment involving an explosive device.
