    Radio Hat 1949 Man-from-Mars

    @sur_27In 1949, you could buy a radio built into a pith helmet for $7.95. Called the “Man-from-Mars Radio Hat,” it had two vacuum tubes, a loop antenna, and a battery pack, picking up stations within a 20-mile (32 km) radius. A fascinating piece of early wearable tech.

    The image features a woman in a dark coat and white blouse, wearing a distinctive light-colored helmet with antennae on top and a ring-like protrusion on the right side. She is seated on a bench, examining a small object in her hands. The background appears to be a cityscape with trees and buildings. The overall aesthetic is vintage and monochromatic. There is no on-screen text visible.
