Antoinette Letterman Signed Geometric Op Art Mixed-Media on Canvas Framed 1970s

A modern Op Art mixed-media artwork on canvas by Antoinette Letterman. Signed lower left. Circa 1970s. The composition features an intricate tessellation of isometric cube forms rendered in warm tones of beige, brown, sienna, and ochre. Executed with meticulous precision, the composition plays with spatial perception, light, and shadow, evoking the illusion of a three-dimensional structure folding inward and outward. The work recalls the visual strategies of Op Art pioneers like Victor Vasarely and Yaacov Agam, where repetition and geometry create hypnotic spatial depth. A compelling piece for collectors of optical art, geometric abstraction, and mid-century modern aesthetics. From a private collection. Dimensions: 37.25"d x 27.25"w x 1.25"d (framed).
