serving as representative examples of the early PRC international postal system. During the 8th Postal Tariff Period (1 January 1955 - 31 August 1956), the aerogramme rate was 38 fen, and in the 9th Postal Tariff Period (effective from 1 September 1956) it was adjusted to 35 fen. Six of the items are international aerogrammes and remittance letters, most uprated with R series issues and bearing “PAR AVION / 航空” markings, addressed to destinations in Southeast Asia and Europe, including two remittance letters with original contents relating to remittance correspondence, vividly reflecting the realities of overseas Chinese communication. Also included is one airmail cover sent to Malaya. Collectively, the group illustrates the structured operation of the PRC postal system during the 8th–9th tariff periods, when aerogrammes and airmail letters coexisted, providing valuable reference material for the study of mid-1950s postal rate reform, route transit, and overseas Chinese postal exchanges.

this large commercial cover, weighing approximately 250g, is franked with sixteen stamps, totaling 270,400 yuan (old currency), slightly underpaid by 20,000 yuan compared to the correct rate of 290,400 yuan. The proper postage consisted of 2,500 yuan for the first 20g of international surface letter postage, 18,000 yuan for twelve additional weight steps, 262,500 yuan for 25 airmail increments at 10,500 yuan per 10g, plus 4,200 yuan registration and 3,200 yuan return receipt fee. The underpayment was likely tolerated by the postal authorities due to minor rounding in accounting or because the actual weight was slightly under 250g, both acceptable conditions for real commercial postings of the period. The cover tied by Tientsin 15.11.50 cds and with Canton 18.11.50 transit & New York 24.11.1950 arrival, having been routed south via Canton and flown from Hong Kong on Pan American Airways (PAA) to the United States. A scarce and remarkable heavy double-registered airmail cover of the early People’s Post period, clearly showing the complex postage composition and operational handling of trans-Pacific mail during the early 1950s. It stands as an outstanding example for the study of early PRC international postal operations and an excellent piece for exhibition.

this cover is franked with thirteen R series issues, totaling 13,000 yuan (Old RMB), paying the correct rate for a 20g airmail letter to “Other Countries”, 2,500 yuan for the first 20g surface postage plus 10,500 yuan for the 10g airmail surcharge. Postmarked Pingyin 51.8.18 cds with Canton 51.8.31 transit, the cover was routed via Canton to Hong Kong, then carried by Pan American Airways (PAA) to England. A representative example of early PRC airmail to Europe during the Old RMB period, it clearly demonstrates the postal rate structure and the functioning of the trans-Asian and European airmail routes in the early 1950s, making it an important item for postal history research and exhibition.

this cover is franked with sixteen stamps, totaling 27,800 yuan (Old RMB), slightly overpaying the correct rate of 27,700 yuan for a 20g registered airmail letter to USA. The postage comprised 2,500 yuan for the first 20g surface rate, 21,000 yuan for two airmail surcharges of 10,500 yuan, and 4,200 yuan for registration. Tied by Shanghai 50.11.14 cds with Canton 50.11.18 transit and New York arrival. The cover was routed south via Canton and carried by Pan American Airways (PAA) transpacific service through Hong Kong. A fine and correctly rated early PRC registered airmail cover to the United States, clearly illustrating the high-rate postal structure of the Old RMB system and the reestablished transpacific route in the early years of the People’s Post, a significant item for postal history and exhibition study.

the cover is franked with four stamps, totaling 11,800 yuan, comprising 2,300 yuan for the first 20g of international surface postage and 9,500 yuan for the airmail surcharge to Europe. The postage was precisely calculated according to the postal rates announced by the People’s Post at the time. After being posted in Shanghai, the cover was routed south via Canton and forwarded through Hong Kong, where it was carried to Europe by Pan American Airways (PAA). Addressed to postwar Berlin in the American occupation zone, this cover represents an early example of international airmail handled by the newly established People’s Postal Service, demonstrating the rapid restoration of China’s international postal connections following the regime change. It is of great significance for the study of postal and airmail history as well as early diplomatic mail routes, and stands as an important artifact documenting the resumption of Sino-European postal communication in the early years of the People’s Republic of China.
