MCM Mid Century Modern Vintage Abstract Enamel on Copper Gold Plate 4"

For sale is a Mid Century Modern enameled copper plate decorated with an abstract design. The base color of the plate is blue. The abstract design uses shimmering tones in gold, orange, green and white. The markings on the back resemble a signature but I am unable to make it out. This plate is beautiful and measures 4 inches in diameter and about 1/4 an inch deep.
