An exquisite selection of works of the late French-born American Abstract Expressionist Yvonne Thomas is currently on view at Berry Campbell. Confident sweeps of wide brushstrokes, organize into vaguely geometric forms that seek to interrogate the psychological potential of color, and summon the ghosts of Robert Motherwell, Mark Rothko, Barnett Newman, William Baziotes, David Hare and Clyfford Still who, together with Thomas, formed the highly influential yet short-lived “Subjects of the Artist” school in 1948. At Berry Campbell through October 7.
