Issued by the Shanghai Local Post Office in 1888, this 20 Cash stamp features the “Small Dragon” motif, symbolizing strength and imperial authority in traditional Chinese mythology. Printed typographically in grey without watermark and perforated 15, it belongs to a definitive series for daily postal use. The design includes a dynamically rendered imperial dragon surrounded by Chinese script and Western inscriptions, reflecting the cultural interplay during the Treaty Port era. This issue is listed as Scott 141, Michel CN-SH 74A, Yvert 69, and Stanley Gibbons 106. It was part of the final local series before integration into the Imperial Post. The example shows a fine strike of a red circular cancellation, clear margins, and intact perforations, though some light gum toning is visible on the reverse. Estimate "$90 – 110"
