Presidents as of 1931

As far as knowledge wheels go, the presidential facts ones aren't high on my list. In fact, I'd say they're almost at the bottom. This one from 1931 is no exception. Who cares where Chester A. Arthur was born? Not me. For my money, the interest is on the reverse: the Geographic Chart of the United States. Check out the 1931 population of Houston (not to mention that of the entire country)!
