25 Pfennig Sozialdemokratische Werbewoche

German political parties issuing their own emergency money during the Notgeld period was not unheard of, but the SPD doing so in Emden is a sharp illustration of how thoroughly the Notgeld phenomenon had penetrated civic and organizational life by 1921. This note was issued specifically to fund a Social Democratic promotional week — "Werbewoche" meaning a membership or publicity drive — making it propaganda material and circulating currency simultaneously. Emden's SPD chapter was operating in a strongly working-class port town, which gave the exercise a particular local resonance.

The DeNG classification places it firmly within the documented Notgeld corpus rather than treating it as ephemera, though the print run almost certainly was small.
