This striking high-value stamp from Imperial Russia, issued in 1875, depicts the majestic double-headed eagle, the emblem of the Russian Empire, within an ornate oval frame. The denomination of 3 rubles 50 kopecks is inscribed in Cyrillic at the top and bottom, making it one of the most prestigious values of its time. Printed in green and carmine, this imperforate issue stands out for its bold design and rich coloring. Such high-denomination stamps were primarily used for heavy parcels or international correspondence, and surviving examples are highly prized. A rare and significant piece for advanced collectors of classic Russian philately.
