The Menil Collection in Houston is showcasing works from a monumental promised gift of Outsider Art in the exhibition As Essential as Dreams: Self-taught Art from the Collection of Stephanie and John Smither. The bequest, which includes fifty works by such luminaries as Thornton Dial, Sister Gertrude Morgan, Solange Knopf, and Martín Ramírez, comes from the late, Houston-based arts patron and collector Stephanie Smither and her husband, John, who died in 2002.
