Vintage Gene Shelly Black beaded wool sweater

Black, wool, sleeveless sweater with exquisite beading around the neckline. Zip and hook closure in back. The sweater is in immaculate condition with no pilling or signs of wear. There is a tiny hole at the left shoulder (pictured) about the size of the tip of a ballpoint pen. The inside is partially lined in the back and there are spots where the lining has come unsewn from sweater. This brand was popular in the 1940s and 1950s and is known for the intricate beadwork on many of their pieces. The bust is approx 20 inches, length is approx 21 inches. No size is indicated, however based on measurements I think it would comfortably fit a M or L.
