This is my entry for Mono Monday - invented in the 19th Century
"In the 1860s, a politician, printer, newspaper man, and amateur inventor in Milwaukee by the name of Christopher Latham Sholes spent his free time developing various machines to make his businesses more efficient. One such invention was an early typewriter, which he developed with Samuel W. Soulé, James Densmore, and Carlos Glidden, and first patented in 1868. "
This one is a Corona 3 portable folding typewriter. My husband and I used to use it to type letters. It only has 3 banks of keys and a different shift key for capitals and other stuff so it was a challenge to use! Apparently it is a 'collectible' now.
The extra shows it folded.
