Beskrivning:

The keyboard of the Malling-Hansen writing ball, invented in 1865 by Danish churchman Rev. Rasmus Malling-Hansen and first produced in 1870. It was the first commercially produced typewriter. Although as in many early typewriters, the page is not visible as it is being typed. As late as 1909 the writing ball was still being used in European business offices.
