Label for a roll of paper for Olivetti/Underwood adding machines
Before digital calculators, adding machines were electrically powered mechanical contraptions. Data was input using a simple keyboard and the data was displayed printed out on a continuous roll of paper. The document shown here is the label/wrapper of such a roll. It was intended for use with Olivetti and Underwood calculating machines and probably dates from the late 1960s or early 1970s.
