Vintage Pink Satin Glass Flower Frog, Oval

This pink satinzied (frosted) oval flower frog arranger is in excellent condition, no chips, cracks, or marring to the finish; could use a better cleaning for surface dust in holes. Measures 5 1/2" long, 2 3/4" wide and 1" high. I haven't identified the maker; it's from an estate of many Cambridge and Fostoria flower frogs.
