This mint never hinged sheet from the Russian Post Office in China, issued in 1917, features 50 stamps originally denominated at 70 Chinese cents, with a bold diagonal black surcharge reading “10 CENTS” applied across each stamp. The underlying design, printed typographically in brown and orange, displays the imperial Russian double-headed eagle within an ornate cartouche—one of the last symbols of the Romanov monarchy before the Russian Revolution led to the closure of Russian post offices abroad. This issue, perforated comb 14 x 14½, measures 18 x 24 mm per stamp and was intended for use in Chinese treaty ports such as Shanghai and Tientsin. The full sheet remains intact with clean selvage, a prominent central gutter, and shows only minor corner creases on the reverse—no hinge marks or gum disturbances. Its historical relevance lies in the turbulent year of 1917, when the Russian Empire collapsed, and communication networks like this one marked the end of an imperial presence in East Asia. Catalogued as Michel RU-CH 47, Scott RU-CH 62, Yvert et Tellier RU-CH 48, Stanley Gibbons RU-CH 54, and Unificato RU-CH 48. Estimate "$180– 300"
