80 Baht / 80 Ticals Banque de l'Indo-Chine

The 80 Baht denomination is the anomaly here. Most Bangkok branch issues from this period followed conventional round-number denominations; 80 was chosen specifically to align with the tical-to-franc exchange rate then current, making the note function as a de facto cross-currency instrument for French commercial interests operating on the Siamese border. The Banque de l'Indo-Chine held a concession to issue in Siam — a rare privilege for a foreign bank in a nominally independent kingdom.

Bramtot was a Prix de Rome laureate; Wullschleger engraved for the Banque de France. The pairing was not unusual for Parisian prestige printing of the period, but it is a reminder that the Indo-China branch notes were produced to metropolitan standards, not colonial shortcuts.
