Round mirror in cut copper, sun-shaped 1970

Round mirror in red copper and small central edge in yellow copper. Laminated edges and edges of slightly notched slats. The slats can be moved slightly up and down and from left to right. Two rings are welded at the back to hang the mirror (one large and one small) The mirror (the tin) has some small visible traces (see photo) There are traces on the copper: I bought it totally black. You couldn't see the little yellow edge. After cleaning, there are a few small traces on the exposed part and a few small corrosion points visible on the reverse on the copper. Reverse to clean.
