Design: The star between the words of the label name is all that remains of the original design. The 'fox-trot' (which here has resisted translation into German), originally known as the 'bunny hug,' was popularized by influential American ballroom dance teachers Vernon and Irene Castle, and was based on a jazz rhythm popularized by famous bandleader W.C. Handy. Note that in the German text, the long 's' is used in the Roman lettering, as it would have appeared if set in Gothic.
History: Thanks to collector Georg Richter of Germany for the following updated info re the history of Polyphon: "The original Polyphon (from 'Polyphon Werke') did not merge with Polydor [as earlier suggested here]. The DGG ('Grammophon') became a subsidiary of Polyphon for political reasons, so the Polydor (an export label of DGG before the end of WWII) was also under Polyphon ownership."

Collector Dimitar Malchev of Bulgaria also notes: "The 'Salome' foxtrot by Robert Stolz was written in 1919, so this record couldn't be earlier than 1919, or 1920-21, when this song became popular all over Europe."
