American, 1912-2016). Backgammon III, 1972, Acrylic on canvas. Verso signed, titled and dated. Artwork is an abstract geometric painting which is likely part of the artist's series of hard-edged geometric canvases. The painting features a symmetrical design resembling a backgammon board, with alternating black, white, and reddish-brown triangular shapes arranged in two halves. The colors are flat and evenly applied, characteristic of Thompson's impersonal approach to paint application, emphasizing sharp composition and clearly defined areas. This style aligns with the hard-edge painting movement, which focuses on precise, clean edges and flat, unmodulated color areas. Thompson adopted this style in the late 1960s, moving away from earlier, more figurative work.
