Space Adventures #48

This November 1962 Charlton offering features a striking Dick Giordano cover split dramatically between light and shadow — a red-suited spaceman armed with a pistol strides forward flanked by robotic figures, while their dark mirror-image duplicates loom on the right half of the image. The cover text promises "The Ambassador from Earth," teasing a story where an amazing duplicator is used on a daring spaceman with intriguing results. It's a wonderfully atmospheric piece of early-'60s sci-fi comics, with Giordano's clean linework giving the concept a cool, eerie elegance.
