This scarce issue from the French Post Office in Mong-Tzeu, Yunnan, is part of the “Indochinese Women” series featuring the refined portrait design by Jules-Jacques Puyplat, printed at the Imperial Printing Office in Paris. Issued in 1919, this 2 centimes brown and black stamp bears the distinctive red “MONGTSEU” overprint along with a new value surcharge of 4/5 centime, a rare fractional denomination reflecting specific postal rate adjustments of the time. Produced by typography on unwatermarked paper with perforation 14 x 13½, this stamp is both a philatelic and historical testimony to the French colonial postal network in southern China. Stamps with such surcharges were intended for limited practical postal use, often in remote locations where rate modifications were required. The portrait motif represents allegorical femininity common in French colonial design, while the surcharge highlights the administrative complexities of early 20th century Indochina-China postal e xchanges. Catalogued as Michel FR-IC B68IV, Scott FR-MT 52, Yvert et Tellier FR-MT 52, and Stanley Gibbons FR-MT 52, this issue remains desirable among collectors of French Colonies and Chinese Treaty Port postal history. Its rarity is enhanced by the modest surviving numbers in fine condition, with similar examples realizing strong prices in recent international auctions. Estimate "$100 – $150". Condition: Fine used, clear surcharge, centrally struck cancellation, intact perforations, light traces of handling on reverse.
