franked with five Kwangtung Silver Yuan stamps of 1 fen each, totaling 5 fen, tied by Amoy cds dated 49.09.14. The franking correctly pays the domestic letter rate of 5 fen. The adhesives, Kwangtung Silver Yuan issues, were used outside their original postal district in Fukien, representing a cross-district usage. Following the invalidation of the Gold Yuan in Aug 1949, restrictions on regional stamp usage were no longer strictly enforced; combined with uneven stamp supply, Silver Yuan stamps from other districts circulated and were accepted for use elsewhere. This cover is a clear example of Kwangtung Silver Yuan stamps used in Fukien. The cover is a commercial envelope of the Standard-Vacuum Oil Company, showing the coastal postal route from Amoy to Swatow, and combining cross-district usage with commercial correspondence. According to current records, such cross-district usages of Kwangtung Silver Yuan stamps are extremely rare, with only seven examples recorded, making this a significant item for the study of Silver Yuan period stamp circulation and the transition of postal district regulations.
