This complete mint never hinged set from the 1943 Sinkiang provincial issue of the Republic of China features surcharged overprints on the Dr. Sun Yat-sen definitive series, ranging from 10 cents to 5 dollars. Produced at the Central Trust Print Works, these stamps reflect the political and administrative autonomy exercised by provincial governments in wartime China. Each stamp is typographically overprinted in black or red with vertical characters indicating usage within Sinkiang Province, a strategic region bordering Soviet Central Asia. Printed by the Central Trust using typography, the set includes values in varied colors including green, brown, vermilion, and carmine. The stamps measure 23 x 27 mm, have a perforation of 12½, and were issued ungummed, conforming to local printing practices during material shortages. The series carries historical importance for its association with the wartime decentralization of authority and the symbolic affirmation of Sun Yat-sen's legacy across remote provinces. It is catalogued as Michel CN-IM-SI 178–189, Scott CN-IM-SI 162–173, Yvert et Tellier CN-IM-SI 124–135, Stanley Gibbons CN-IM-SI 227–238, and China Stamp Society CN-IM SK205–216. Condition: Excellent MNH set with fresh colors and full margins throughout. Estimate "$280 – 350".
