I have seven different pairs of these earrings with this makers mark on the back. It's from my MIL's estate and may be from the 70's. Not sure of the metal, probably brass. Looking to list and would like to know more about them if anyone can help. TIA.

They may be from a small artist sold at a local fair. You might ask on one of the jewelry forums or groups: https://community.ebay.com/t5/Jewelry/bd-p/Jewelry https://community.ebay.com/t5/Jewelry/ct-p/1117
