True turn-of-the-century antique Art Nouveau brooch featuring a very detailed rendering of a lady in profile with flowing hair decorated with flowers. The sterling brooch is 1 and 1/8" wide by just over 7/8" tall. The pin is marked STERLING and it has a makers mark: L&A. Unfortunately I was unable to identify this maker, if anyone has any info please let me know! The brooch is in excellent condition with a light patina and no damage.
