In the art world, what's fashionable one year is sometimes passe the next. American artist Thomas Hart Benton is a case in point. Benton was wildly popular in the 20s and 30s -- even making the cover of TIME magazine. But then... with the advent of abstraction.... Benton's realistic paintings of Americana plunged in popularity. Now.... Benton is back. An exhibit of his paintings and drawings is showing at the Minnesota Museum of American Art in St Paul. And Minnesota Public Radio's Mary Stucky toured the exhibit with Kris Wetterlund the museum's director of education.
