Old antique/vintage mirror

FYI- CRAIGSLIST MESSAGING ONLY. NO PHONE CALLS OR TEXT. SORRY FOR INCONVENIENCE. This is a very heavy piece. In fantastic condition. Black and gold Measures approximately 39 & 1/2. By 29 & 1/4 There are 5 or 6 small black lines at various points around the edge of mirror itself. I'm assuming these were for positioning in frame. An example is shown in the pictures. There seems to be very little , if any, oxidation. Gilded frame is beautiful, unbroken and thick.
