Built in the 1920s
Warren Harding took office in 1921, Calvin Coolidge succeeded him in 1923 and Herbert Hoover was elected in 1928. The census of 1920 was the first to count more Americans in towns and cities than on farms. Prohibition was in force and the automobile and the radio spread quickly. The stock market crashed in October 1929.
