SIBYL EDWARDS (Canadian b. 1944) A GROUP OF ELEVEN BLACK AND WHITE OP ART EGGS, oval, circular, and square expressions in monochromatic?watercolor paint on eggshells, largest egg height: 3 1/4", diameter: 2 1/4". Note: A whimsical combination of mid-century op art with folk art; the present collection includes a variety of egg sizes, which is an outsider format, typical of folk art. The egg bulges the hand-painted two dimensional mathematical algorithms. The artist's use of bright color or monochromatic is an exercise in color theory initiated by artists such as Josef Albers and optical illusion artworks by Victor Vasarely and Bridget Riley during the 1950s and 1960s. Provenance: Personal Collection of Roy H. Van Horn, Houston, Texas.
