5 Francs

Banque de la Guyane was established in 1851 as one of France's colonial privilege banks, with a monopoly on note issue in French Guiana. This 5 Francs note spans an extraordinary twenty-five year printing window — the same plate design served through the interwar period, the fall of France, Vichy administration, and the Free French transition, with date ranges suggesting the institution simply kept issuing against existing stock rather than commissioning new designs.

Charles-Jules Robert and Charles Wullschleger were both associated with the Banque de France's engraving workshops, which supplied plate work to the colonial issuing banks. The designer credit to Harang under the pen name Cabasson is the more unusual detail — pseudonymous design credits on colonial paper money are uncommon enough to be worth noting.
