Grandmother's opera glasses

My sister brought these opera glasses to me that belonged to my grandmother Seelye. They are silver and are tarnished. The extra shows the pretty blue of the inside of the case. Unfortunately the case is falling apart. Her name was Helen St. Barb Eustis Seelye...a mouthful. St. Barb her middle name, Eustis her maiden name, and Seelye name by marriage. She was born in 1880 so these would have been sometime after the turn of the century. Seelye is my given middle name and what I go by, but family and a few friends call me Susan :-)
