What it is

A vulcanised rubber stamp moulded from a matrix of type, used to imprint dates, signatures and repetitive text. A humble but ubiquitous tool of bureaucracy and commerce.

The origin is uncertain: James Orton Woodruff (a native of Auburn, New York) is said to have made them in New York after the American Civil War using his dentist uncle's vulcaniser; L. F. Witherell (Knoxville, Illinois) claimed 1866 without evidence.
