Friedrichshafen's municipal emergency money from the hyperinflation peak of late 1923 was printed locally by Robert Gessler's widow's print shop — a commercial firm entirely unequipped for currency production in any conventional sense, pressed into service because the Reichsbank simply could not supply denominations fast enough. By the time notes of this face value were being struck by town governments across Württemberg, the purchasing power they represented was already decaying within hours of issue.

The designer credit "Flagg" in the margin remains unresolved — likely a local commercial artist rather than anyone with formal banknote experience.
