This is a 1900 issue from the German colonial offices in China, featuring the German Empire’s imperial eagle design originally used for Reichspost issues. The stamp is denominated at 50 Pfennig in carmine and bears the bold diagonal black overprint “China” to distinguish its colonial use. Such overprints were applied to regular German issues for use in German post offices established in treaty ports across China. These issues are significant as they reflect both German imperial influence and the expansion of foreign postal services during the late Qing dynasty. A sought-after piece in colonial philately, this stamp appeals to collectors of both German Empire and China-related postal history.
