This stamp originates from the German Post Offices in China during the late 19th and early 20th centuries. It is a 10 Pfennig red issue of the German Reichspost, featuring the imperial eagle of Germany, and bears the large black diagonal “China” overprint to denote its use in the German concessions within China.

These overprinted stamps were first introduced in 1900, reflecting Germany’s presence in the Treaty Ports and during the Boxer Rebellion era. Collectors value these issues not only for their striking overprints but also for their strong ties to colonial postal history. Higher values and varieties of these overprints, including inverted or shifted text, are especially sought after.
