Yukaghir birch-bark carvings

The Yukaghir birch-bark carvings were traditionally drawn by Yukaghir people of Siberia on birch barks for various purposes such as mapping, record-keeping, and party games. Russian writers observed these carvings in the 1890s, and based on their descriptions, several 20th-century scholars misunderstood them to be the examples of a writing system. One particular carving became well-known as the "Yukaghir love letter", but is actually the product of a guessing game.
