These classic Imperial Russian stamps feature the iconic double-headed eagle within an ornate shield, surmounted by a crown. The left stamp, denominated 40 penni, is a bilingual issue (Russian and Finnish), primarily used in the Grand Duchy of Finland under Russian rule. The right stamp is a 15 kopeck imperial issue, inscribed entirely in Russian. Both are part of the early 20th-century definitive series, notable for their deep reddish-brown and blue coloring, intricate shading, and strong national symbolism. These unused examples are well-preserved and sought after for Tsarist-era collections.
