I assume the smokiness of this mirror is product of age and circumstance, and the fact that it is tightly sealed inside, so impossible to remove the mirror from the frame in order to replace it. There is really no seam visible at all on the frame, but I believe a piece of veneered wood must have been laid over the backside, glued, and trimmed exactly to match the edge. I of course love the idea of a completely and forever trapped mirror as well as its smoky appearance--still somewhat reflective, but much more about ambiance and mystery.
13 x 11 x 1 3/8”. The solid wood frame is in very good condition, and the whole thing is heavy for its size. With what I believe is a recently added hook to the backside, which wasn't placed very carefully but it easily removed.
