Advert for the Rapid Roller Copier
Medium: Print on paper
19th century clerks had to hand-write every document, and methods of reproduction, such as the standard hand press, were often very time consuming or expensive. This Rapid Roller Copier is in essence a forerunner of the modern photocopier. Original documents were written in copying ink and placed into the machine. The operator would then turn a handcrank, which would impress the contents of the document on to blank sheets of paper. According to this advert, "100 letters can be copied in two minutes."
