100 Francs - Bon municipal de la ville de Saint-Omer church left [62]

Saint-Omer issued its own emergency municipal notes in 1940 because the German advance through northern France in May of that year effectively severed the region from normal banking channels. The Nord-Pas-de-Calais department was placed under German military administration separately from the rest of occupied France — attached to the Brussels command rather than Paris — which created genuine logistical difficulties for currency supply that pushed municipalities toward locally printed bons.

Loïez-Bataille was a local Saint-Omer press, not a specialist security printer, so the notes rely on design complexity rather than technical anti-counterfeiting measures. Vandenbergue's design work is competent but the printing reflects the constraints of a commercial house working under occupation conditions.
