I have collected these gorgeous French sterling silver medals for years and a while back I had several set as button. For that reason, I cannot recommend this for NBS competition. They would consider this a conversion. However, if you appreciate precious metal and the French Art Nouveau design, you may enjoy adding this to your Female Figures :) It measures 1 & 5/16 by 1/8 inches and was made in 1924. She has a lot of bag marks, but I find the finish to add a strangely ethereal dimension to the subject.
