1 Mark Oldenburger Woche

Oldenburg's trade fair notgeld occupies a peculiar niche even within the already chaotic German emergency money issues of 1922. The Oldenburger Woche — the city's annual trade fair — issued its own scrip for use within the fairgrounds, a practice that blurred the line between promotional souvenir and functional small change at a moment when inflationary pressure was making official coins functionally useless. Whether these circulated seriously or were collected on the spot is an open question; fair-specific notgeld typically had a very short redemption window tied to the event itself.

Ad. Essich & Co., the Oldenburg printer, was a local house — Büttner's successor firm — rather than one of the major Leipzig or Berlin notgeld specialists.
