Unusual Tales #27

A man dreams of a machine that takes him down into the earth, where he encounters an engineer who shows him a powerful underground vehicle and warns him that if he takes it for a test drive, he may never return alive. Despite the risk, the man operates the machine and discovers ore in a deep cave, but his greed leads him to push the vehicle to full throttle, resulting in a catastrophic crash that traps him underground. The issue also features a contest offering prizes including trampolines, bicycles, Marx-a-Karts, and footballs to readers.
