This is an old mirror.  I am guessing based off information I got from the previous owner this dates back to the 1920’s.  I believe this was made by hand.   You can tell this is the old original glass.  It has that glass look were there are imperfections to the glass based on the process of making it.  Modern mirrors don’t give that look.  The wood has many chips along the corners and edges.  The size is rather unique.  This is a rustic look.   My client lived in California as a child and this belonged to her parents.  It has a western vibe for sure.  Often times I color frames in.   I have a kit with 100 colors.  I am opting to leave this as is.  Typically on antiques I tend to do that.  Every scratch and chip adds character. This mirror is much heavier than it looks.
