Description
Black and white 9 1/2″ x 13 1/2″ ad for their Adding-Figuring Machines. There is a picture of a young, blonde office worker using one of these machines as the tape full of calculations wraps around her head. The headline claims that “She lists 4,000 Bank Checks per Hour on an Underwood Sundstrand Adding Machine“ and identifies her as Miss Evelyn Nelson who works for “a well-known banking institution”. She is quoted as saying that “Touch operation and speed listing come naturally on a 10-Key Underwood Sundstrand“ and the text indicates that she was timed while doing 296 checks, “checks she had never seen before”, and this was expanded to estimate 1.12 checks per second or 4032 checks per hour. The ad talks about the 3-Point Control which is 3 miracle keys that perform 6 important functions and claims “there is at least one model that is ideally suited to your requirements”.
