Gillender Glass Shoe 1876 Etched M. Savage

Antique glass shoe made by the Gillender Co., for the 1876 Philadelphia Centennial.  Embossed in the bottom of the shoe is Gillender Co Centennial Expo.  Etched on the side of the shoe is M. Savage.  Some of the glass edges have light chipping, nothing major, a few at the bottom front of the shoe where the glass edge is sharp.

I have another shoe like this one listed here, with no engraving.

This shoe is approx. 4 1/4 in length and 2 1/2 inches tall.
