China 1890, Double Dragon issue from the Treaty Port of Shanghai, featuring a 2 Chinese cents denomination in brown. Lithograph printed with a perforation of 12, this stamp displays two imperial dragons encircling a traditional coat of arms, a powerful symbol of Qing sovereignty adapted for foreign-administered postal use. It bears the watermark “Ministry of Industry” (characters facing up), used to denote official production during the early stages of China's semi-autonomous treaty port postal systems. Cataloged as Scott SH 125, Michel CN-SH 100, Yvert et Tellier CN-SH 84, and Stanley Gibbons CN-SH 125. This example is postally used with a clear Shanghai circular date cancel, deep coloration, and fine design clarity, with minor wear at edges consistent with period handling. Estimate "$95 – 120"
