Vintage 1950's Black and White dangle statement clip on earrings Signed

These gorgeous Vintage black and white Cluster dangle statement 1950's clip On earrings are signed, due to age and the way they were kept I can not make out the markings. I got all my jewelry from a woman who was a collector and maker of jewelry from the 1930's til the early 2000's. unfortunately they were not stored good. They were in boxes in a shed for years. She definitely knew what she was doing back then. I do as much research as I can, please see all pictures
