Zweibrücken's 1918 emergency issue came at the tail end of the wartime Kommunalnotgeld wave, when municipal authorities across Germany scrambled to compensate for the hoarding and disappearance of coin from everyday commerce. The city's treasurer Haremann and mayor Oesinger both signed, which was a deliberate legitimizing gesture — dual authorization gave the note quasi-official weight in a period when public trust in paper was already badly strained.

DeNG 3#582.02 distinguishes this as a specific print variant within the Zweibrücken series, suggesting at least one other type was issued concurrently or in close succession.
