1000 Francs

The Banque de l'Algérie's 1000 Francs series spans a politically charged window: the 1918 dates fall within the final weeks of the First World War, when French colonial currency demands were acute and metropolitan printing resources were stretched. The note was engraved by two distinct hands — Robert on the obverse, Wullschleger on the reverse — a division of labor more common in this period than collectors often recognize, particularly on high-denomination colonial issues.

Harang, who worked under the pseudonym Cabasson, was among the more prolific designers supplying Banque de France affiliate institutions during this era. The shift in the third signatory from Biron to Penalva between the 1918 and 1923 date ranges marks an administrative change worth noting when dating individual examples.
