A small, 8"x8" fresco relief titled Opposition of Forms sold for $8750, above its estimate, at Sotheby's auction of Property from the Collection of Nelson and Happy Rockefeller.  The tempera on marble piece was signed 1945 and was purchased from the Downtown Gallery, run by Edith Halpert. Rockefeller's mother, Abby Aldrich Rockefeller, was an early anchor of the Gallery which promoted American art, including Folk art in the l930's.  Nelson Rockefeller worked closely with Halpert on large contemporary art shows in the new Rockefeller Center in the Depression. This piece was most likely included in one of her shows of "small works", illustrating her acumen of inventing ways to attract clients.
