Art Brokerage: Sam Gilliam African-American Abstract Painter: b. 1933. America's leading black artist, Sam Gilliam's painterly abstraction concerns itself with saturated color and a highly improvisational and spontaneous technique. During the late 1960's Gilliam's interest in the flexible properties of canvas led to his innovative manipulations of both canvas and paper and a series of work which were created and subsequently hung or suspended without traditional stretcher supports. Gilliam's explorations in the areas of printmaking have been equally dramatic and have included the use of handmade papers and paper pulp, dyes, and paints combined with a combination of stitching flocking, embossing, collage, and screenprint techniques.
