Todd Personal Protectograph Model 1500

by Dave Weller

This is a protectograph. Also called a check writer, this machine is a physical device for protecting a check by preventing the monetary amount, for which it was written, from being raised or altered. This particular model was primarily used by small businesses.

My wife remembers playing with this one in her dad’s office. i don’t know where he acquired it from.

It was manufactured by the Todd Protectograph Company in Rochester, NY. Patented in 1923, it was advertised from 1925 to 1930.
