This 1917 stamp issued by the British Post Office in China features a standard Hong Kong definitive of King George V, overprinted with the word “CHINA” to denote usage exclusively within the British treaty ports of China. Printed typographically by De La Rue & Co. Ltd. and Somerset House, the stamp is part of a larger series reflecting colonial administration and imperial communication networks in the Far East. The portrait of George V—framed by classical ornamentation—appears above the denomination in Chinese cents, with the overprint applied in bold sans-serif capitals. The watermark is the multiple Crown over Block CA, upright, and the stamp is perforated line 14, measuring approximately 20 x 24 mm. Used primarily in British-controlled postal facilities such as Shanghai, Tientsin, and Amoy, these overprints served both practical and symbolic functions, asserting imperial presence and regulating mail usage within a defined jurisdiction. This issue represents the height of British colonial philately in China during the waning years of treaty port dominance. Condition Postally used with partial cancellation, well-centered, minor age wear, strong impression and clear overprint. Estimate "$90 – 120".
