American Regionalism

From Wikipedia: 

In Grant Wood's pamphlet Revolt Against the City, published in Iowa City, 1935, he asserts that American artists and buyers of art were no longer looking to Parisian culture for subject matter and style. Wood wrote that Regional artists interpret physiography, industry, and psychology of their hometown, and that the competition of these preceding elements creates American culture. He wrote that the lure of the city was gone, and hopes that art of the widely diffused "whole people" would prevail. He cites Thomas Jefferson's characterization of cities as "ulcers on the body politic."
