This commercial cover sent from Canton (Guangzhou) to San Francisco in 1915 features a single 10 cent dark blue stamp from the renowned “Junk, Reaper, and Hall of Classics” issue of the early Republic of China, printed by Waterlow & Sons Ltd. in London. The stamp, gravure-printed and perforated line 14, is part of the first definitive series of the Republic, capturing national identity through maritime imagery. The design shows a Chinese junk sailing leftward with full sails, symbolizing trade, exploration, and progress. The envelope bears a vivid pair of red oval merchant chops from "Gee Wah Hong", with traditional Chinese and romanized text indicating their location in Hoi Ping District, Canton. The reverse carries dense calligraphy in black ink, likely part of the original business correspondence. The addressee, Doap Luen Hong & Co. in San Francisco’s Grant Avenue, links the item to the transpacific Chinese diaspora and merchant trade networks of the early 20th century. Minor creases and aging are consistent with carriage across the Pacific but do not detract from its philatelic appeal. The stamp is catalogued as Michel CN-IM 158I, Scott CN-IM 211, Yvert et Tellier CN-IM 155, Stanley Gibbons CN-IM 77, and CSS CN-IM 249. Estimate "$75 – 100"
