"Dial's work has sometimes been described as "outsider art", a term that attempts to cover the product of everyone from naive painters like Grandma Moses to institutionalized lost souls like Martín Ramírez and full-bore obsessives like Henry Darger, the Chicago janitor who spent a lifetime secretly producing a private fantasia of little girls in peril. But if there's one lesson to take away from "Hard Truths: The Art of Thornton Dial," a triumphant new retrospective at the Indianapolis Museum of Art, it's that Dial, 82, doesn't belong within even the broad confines of that category....What he does can be discussed as art, just art, no surplus notions of outsiderness required....And not just that, but some of the most assured, delightful and powerful art around.
In 1993, Dial's work was the subject of a large exhibition that was presented simultaneously at the New Museum of Contemporary Art and the American Folk Art Museum in New York. In 2000, the artist's work was included in the Whitney Biennial, and in 2005-06, the Museum of Fine Art; Houston presented a major exhibition entitled "Thornton Dial in the 21st Century". Dial's works can be found in many notable public and private collections, including those of, among other institutions, the High Museum of Art, the Museum of Fine Arts, Houston; the American Folk Art Museum, New York; the Philadelphia Museum of Art; The Hirshhorn Museum and Sculpture Garden, Washington D.C.; the Smithsonian American Art Museum, Washington D.C.; and the Indianapolis Museum of Art."Wikipedia
