1 Franc - Chambre de Commerce de Périgueux 24

French chambers of commerce were authorized to issue emergency small-denomination notes during and after the First World War to compensate for the near-total disappearance of metal coinage from circulation. The Périgueux chamber's notes from this period were printed locally by Ronteix rather than by one of the major Paris houses — an unusual choice that kept production costs and turnaround time within the Dordogne itself. L. Pigeon's design credit appears in the plate, though little else about this designer survives in the commercial printing literature of the period.

JP#98-26 places this as the 24th documented type in the Périgueux series, reflecting just how many successive issues the chamber required to sustain local commerce through the postwar monetary disruption.
