The Mignon AEG typewriter is a unique technological relic from the end of the 19th century. It is an index typewriter, which means that typing is done using a pointer that is moved over an index with a list of characters. When you select a character, you set the pointer, and its movement translates into a change in the position of the type head, allowing the character to be printed on paper.

The Mignon AEG typewriter was produced by the company Europa Schreibmaschinen A.G. in Berlin-Erfurt, Germany. It is an example of the advanced technology of that time, which significantly accelerated and simplified the typing process.
