This full sheet of 60 used stamps originates from the Shanghai Local Post Office during the Qing Dynasty and features a rare unlisted provisional overprint converting the 2 cent denomination to 1 cent. The overprint is distinguished by a unique “double break edge” in the surcharge, a variety not recorded in standard catalogues such as Chan. The underlying design showcases the iconic Double Dragon motif, printed via lithography and perforated 12, reflecting the artistic symbolism and administrative function of imperial imagery in Chinese postal iconography. Issued around 1893, these stamps were produced for use within the semi-autonomous treaty port network at a time when the Qing government allowed limited local postal control in key trading cities such as Shanghai. The Double Dragon design—evocative of imperial authority and celestial protection—was a central element in early Chinese philately and became a recognizable emblem of Qing-era postal sovereignty. The sheet presents uniform usage with consistent cancels, likely struck in Shanghai, and features strong impressions, balanced margins, and excellent alignment. Condition Very fine used with legible circular postmarks across the sheet, no visible faults or tears. Estimate "$480 – 600".
