20 Piastres

The Banque de l'Indo-Chine's early 20th-century piastre notes were printed by the Banque de France — an arrangement that reflected the colonial bank's close relationship with French financial institutions rather than any emergency or outsourcing necessity. Wullschleger was a prolific engraver for the Banque de France during this period, and his work on the Indo-Chine plates shows the same fine-line intaglio technique applied to metropolitan French issues of the same decade.

Bramtot, better known as a Salon painter and medallist, contributed figure designs that were then adapted for the engraved format by Wullschleger — a common division of labor in French note production at the time. The 1905–1907 dating window for P#15 reflects sequential issue batches rather than a single print run, and surviving examples with legible date notations help narrow individual pieces within that range.
