oval convex glass, vintage replacement for domed bubble glass picture frame

Oval shaped convex glass for an antique or vintage picture frame with the curved glass 'bubble'. This is a vintage piece, used but in good condition with very little scratching.

This one measures 1" deep at the center, 6 3/8" x 8 5/8". Edges and shape are hand formed, not perfect by the very nature of the manufacturing process. We have just one in this size.
