For sale here is a RARE and wonderful vintage 1960s 70s original copper enamel abstract modernist op art wall hanging artwork by San Diego California craftsperson enamelist Phyllis Wallen. This work is untitled, but I call it "Blues" because it's a study in shades of blue from pale pastel blue-green at one end to a dark rich cobalt blue at the other end with fields of geometric flowers alternating with parallel lines and gold circles. Subtle but powerful composition by an enamelist often considered one of the best in the country from the mid to late 20th century! Measures just under 24-3/4" wide by 7-1/2" tall. Marked at back with original sales stickers as shown. At one end the wood is very slightly warped which has raised one panel less than a millimeter above the one next to it, but this is not at all noticeable when hanging on the wall. Excellent vintage condition with just minor edge wear in a few spots as shown in my closeups - please view the photos, read the description, and ask all questions prior to purchase. I am open to reasonable offers from serious buyers.
