Antique Early 1900s Two Sided Open Locket on Fob Chain

This is a different kind of locket.

It dates to the early part of the 1900s. It opens by gently unscrewing the piece at the top. A special open faced locket that holds two pictures.
I have combined it with a watch fob chain to make it in to a necklace.

This is a very short piece but could be added to other necklaces or adornments.

Chain Length: 12 inches
