This 1919 issue from the French post office in Hoi-Hao, a treaty port in China, features a 15 centime violet stamp from the Indochinese Women series surcharged with a new value of 6 cents and additional overprints in black and red. Designed by Jules-Jacques Puyplat and printed by the Imperial Printing Office in Paris, the stamp displays the finely engraved profile of an Annamite woman set within a detailed ornamental frame. The surcharges reflect the adaptation of metropolitan colonial postage to local currency and postal conditions, a common practice in extraterritorial French postal agencies across Asia. The red Chinese characters denote “Hoi-Hao,” while the large black surcharge adjusts the denomination. Printed typographically on paper with perforation 14 x 13½, the stamp measures 20 x 24 mm. This example is postally used with a partial circular date cancellation and clean reverse, showing only faint hinge traces. It is catalogued under Scott FR-HH 72, Michel FR-IC B72II, Yvert 71, and Stanley Gibbons 71, and represents a notable intersection of French colonial aesthetics and Chinese overprint culture.
