"Telautograph" copy telegraph, encoder (right) and receiver (left)

This map is much larger and more detailed than the maps received with a "Fultograph." It probably served as a template for further use, presumably in newspapers or as a public poster. Since it mainly includes Frankfurt weather data, it could also have been used for air traffic control in Frankfurt (back then still known as the "Frankfurt Rebstock Airport" in the Bockenheim district).
