Before the invention of the photocopier, people had to rely on all sorts of different techniques to make copies of correspondence and text. In the 1780s there was letterpress copying where a dampened sheet of thin tissue paper was laid against the inked side of an original document and then put in a press. The two sheets were pressed together producing a mirror image of the original text on the tissue. Due to the tissue’s semi-transparency, when it was held up to light the mirror image text could easily be read through from its back.
