Chinese Typewriter (Dec, 1947)
Chinese Typewriter has 72 keys and 576 characters. You press two keys at the same time, one for the top part of a character and one for the bottom. This puts eight words into printing position. You select and print the word you want by pressing one of the eight white keys.
That looks like it’d be awfully cumbersome to type with! I bet it was made by Mr. Typewriter, too.
