This 6-kopeck Soviet stamp, issued in 1976, commemorates the historic icebreaker Ermak. Built in 1898 under the direction of Admiral Stepan Makarov, the Ermak was the world’s first true Arctic icebreaker, designed to withstand the harshest polar conditions. The design features the ship cutting through icy seas, with the aurora borealis lighting the background, symbolizing its role in Arctic exploration. The bold engraving and contrasting colors highlight Soviet naval and scientific achievements. A fine thematic issue for collectors interested in ships, polar exploration, or Soviet maritime history.
