This coin-operated gramophone with green floral horn worked automatically: by inserting a 10 pfennig piece, a mechanism sets the tonearm as well as the turntable and shellac record in motion, and the music starts. They were manufactured by Mammut-Werke from Leipzig, whose machines were in great demand in restaurants in Germany, Austria, and Bohemia at the beginning of the 20th century. A plaque states that the merchant Albert Kettner in Rosenheim, Bavaria sold the gramophone.
