Cover of Science and Invention 10, no. 6 (October 1922)

In red type, the masthead features above a man sitting at a desk, his back to the reader. Before him on the desk is a tall machine with gears and dials, labelled “Radio Typewriter Co.” It's spinning out pages like a printer, and from those pages the man is holding up one sheet, reading it to himself. The caption reads, “Letters Now Sent by Radio.”
