1893年10月11日厦门寄九龙一分邮资封, 加贴上海书信馆双龙弍分票, 销厦门书信馆代办带 "D" 字蓝色日戳, 及厦门书信馆双语戳. 当时香港并不不属于上海书信馆邮政系统, 少见以九龙为目的地. 信封保存良好.Amoy Agency of the Shanghai Local Post 1893 (11 Oct.) Shanghai 1c. postal stationery envelope (E1a) addressed to Diercking in Kowloon, uprated with Double Dragon 2c. which is tied by "<H>local post agency/amoy" code "D" c.d.s. in blue and a good strike of the "<H>amoy local post/agency" postmark in blue alongside. Clean and fine and a good destination as Hong Kong was not part of the Local Post System. Photo
