United States Chart of Knowledge; names of states on edge; center portion revolves to reveal information about each state; reads "United States Chart of Knowledge / Made in USA by Chart of Knowledge Co. of America. Boston, Mass / Copyright 1931 / Pat Pending 523044 / S.C. Bocholtz, Boston."


To help students learn about each state in the U.S., the Chart of Knowledge Company published this two-part wheel decorated with a map of the United States, Canada, Mexico, and Alaska. When the user moved the top wheel and the red arrow pointed to a state’s name, the blue windows on the chart showed information about the state, such as geographic features, important products, and population.
