About this book
Rapid Mechanical Calculation / Comptometer Adding & Calculating Machine Operated by Keys Alone
Author: Felt & Tarrant Mfg Co., London
Year: 1913
This promotional booklet describes in detail what a Comptometer is and how it can aid in business. This was probably a free booklet would be sent to anyone in the who replied to an advert to request more information. It contains a separate supplement which lists the many companies that were already using Comptometers. Note that this is the U.K. edition - it has London rather than Chicago on the title page, and the testimonials and the supplement's list of users are from the U.K. only. The booklet does not contain any publication year, but it mentions the model E Comptometer so it probably came out in the same year as that model, about 1913.
