The artworks created by a so-called outsider, art brut, and self-taught artists have fascinated viewers for decades. The Hidden Art captures the evolution and growth of this art field, narrated through the outstanding collection that Audrey B. Heckler has meticulously assembled over the last 24 years. Organized into five sections—Masters, Art Brut and Self-Taught Artists in Europe, American Classics, Southern Self-Taught Favorites, and 21st-Century Self-Taught Art Worldwide—this publication celebrates the individual contributions and legacy of self-taught artists with thoughtful essays by thirty-two renowned specialists of self-taught art, who represent the international scope and diversity underlying this collection. Written by Valérie Rousseau (ed.); Preface by Anne-Imelda Radice; contributions from Jane Kallir and 29 additional scholars. Photography by Visko Hatfield. New York: Skira Rizzoli/American Folk Art Museum, 2017.
