50 Centimes - Région Economique du Centre

France's post-WWI economic regions were administrative constructs created in 1919 to manage reconstruction and coordinate industrial recovery across war-disrupted departments. The Région Economique du Centre — covering the Loire basin and surrounding areas — was among the least industrially dominant of these groupings, which likely explains why its fractional emergency issues remain modestly documented. By 1924, most municipal and chamber of commerce emergency notes had already been retired across France; this issue appeared unusually late in the cycle.

B. Arnaud of Villeurbanne, a Lyon suburb, handled a significant volume of regional French emergency paper during this period. The JP#40-5/6 reference places this within a small series.
