This early 1900's domed patterned black glass button is wonderful. At 1 1/4" round and 1/2" deep it has a metal shank. It is in excellent condition with tiny edge chips that are not visible from the top. It can be used for so much....Hanging on a silver chain at the neckline....on a bracelet...or as a button on your special card. Lovely pressed geometric embossed pattern.
