1 000 000 000 000 Mark linen issue

Bielefeld's Stadtsparkasse issued this note on linen rather than paper during the 1923 hyperinflation crisis — not as a novelty, but because paper stock had become unreliable and the city's textile industry made fabric a genuinely practical alternative. Bielefeld, a center of the German linen trade, had both the material and the local printer to make it viable. E. Gundlach A.G. produced the run locally, keeping the entire operation within the city.

The denomination — one trillion Mark — dates this to the absolute peak of the inflation spiral, when such figures had become arithmetically necessary for daily transactions. Linen examples from this series survive in better condition than paper contemporaries, the weave resisting the kind of fold damage that destroys paper notgeld.
