There is no visible signature or maker's mark on the piece. Possibly on reverse but it is completely cover by a heavy felt material. It is in excellent conditioned for what I preceive as its age. Mirror surface is in excellent conditioned... no silvering. Raised inlayed material (appears to be animal bone) shows stress appropriate with age. Decorative metal border is also in excellent condition. The only condition flaw is the felt that has come off at the bottom of the "foot" part of the mirror.
The mirror measures 38" to the shoulder and 42" to the tip of the catheral top. It is 1" in depth and 21" in width.
