| Hard Edge Abstraction c 1958 - c 1969 USA A term first used in 1958 by an L.A. critic to describe the abstract canvases of West Coast painters uninterested in the brushy gesturalism of Abstract Expressionism. In 1959 this term was used to describe American paintings with surfaces treated as a single, flat unit. It overlaps with Color Field painting, but is generally more precise, clean, and impersonal. Also called Hard Edge Painting. | |
