Hohner advertising brand "Trachtenpaar", manufactured by the company "Jos. C. Huber, Diessen vor München".
The first advertising poster for Hohner "Accordeons" undoubtedly served as a model. The poster in question was created in 1903 by the Freiburg advertising graphic artist Fritz Reiss and also used as an advertising postcard.
Not as detailed as the role model painted by an artist, the miniature with its folk costume looks appealing.
