1931 Knapp Volvelle Map of the United States and Europe

A wonderful educational tool, this is a fully functional 1931 A. Knapp volvelle map of the United States and Europe.

A Closer Look

With the United States on one side and Europe on the other, the central disc on both sides spins so the red arrow points to a state or country along the outer ring. On the United States side, information included on the outer ring is the state's name, nickname, and number on the map. By numerically identifying the states, the volvelle provides a geography lesson alongside interesting facts. As the wheel turns to each state, population, square mileage, capitol, main river, and the year it entered the Union appear in windows cut into the central disk. An illustration of the U.S. Capitol Building in Washington, D.C., and statistics concerning the continental United States and the highest and lowest points in North America adorn the central disc as well.

On the European side, the country name and map number appear on the outer ring, providing the same geography lesson as on the United States side. The information provided in the windows includes the capitol and its population, the country's total area and population, the type of government, and the time in the country relative to New York City.
