10 Pfennig red issue

Waldenburg — now Wałbrzych in southwestern Poland — was a coal-mining center whose municipal government issued emergency small-change notes when metallic coinage effectively vanished from circulation during the First World War. The "red issue" designation distinguishes this note from otherwise similar Waldenburg Pfennig notgeld printed in other ink colors, a practical differentiation that collectors have carried forward from the original series documentation.

Ferdinand Jovel's Erben was a local printing firm — "Erben" meaning the founder's heirs had inherited the business — and the entirely local production chain, issuer and printer both rooted in the same Silesian coal town, is typical of the smallest notgeld operations.
