50 Heller Neuhaus

Austrian municipal emergency currency — Notgeld — proliferated after the First World War as the new republic's coin supply collapsed almost entirely. Neuhaus im Wienerwald was one of hundreds of small Lower Austrian communities that stepped in to fill the gap, issuing fractional Heller denominations for local retail transactions that federal coinage could no longer support.

The Jaksc reference places this squarely within the documented Lower Austrian municipal series. Guilloche underprinting on notes of this type was often handled by small regional printers working with whatever security tooling they had on hand — consistency across the series is not guaranteed.
