Angle/Edge/Plane: The Sculpture of Ronald Bladen is a collection of models, drawings, and photographs from the estate of Ronald Bladen and the Loretta Howard Gallery in New York. This exhibition was organized The Ewing Gallery of Art + Architecture, University of Tennessee Knoxville, and has travelled to Herron School of Art + Design, Purdue University, Indiana, Peoria Riverfront Museum, Peoria, Illinois, and The Sarah Moody Gallery of Art , University of Alabama.

The first monograph on a pivotal figure of postwar American art.

Ronald Bladen (1918-1988) was regarded as an artistic forerunner by Minimalists like Donald Judd, Sol Lewitt, and Carl Andre. But in contrast to the matter-of-fact work of these artists, Bladen's sculptures are charged with emotional power. They fill entire rooms, pressing outward against the walls and ceiling; their themes include the force of gravity, the dynamism of planar surfaces, the impact of scale, and confrontation with the viewer.
