Vintage Matisse Renoir Enamel on Copper Bracelet

Beautiful vintage Matisse/Renoir enamel hinged bracelet. Fun angular asymmetrical shaped front holds a plaque with swirled designs in blue, green and white translucent enamel. Bright copper, in excellent vintage condition -- I don't see any of the usual scratches or tarnish on the metal.. Under the plaque is a bit of visible glue along some edges, no real issues. The enamel looks great -- I see two hairline cracks that don't go all the way through near the more narrow end, not very noticeable. 1 1/4" at widest point and about 6" all the way around the inside when closed -- could expand another inch or so without looking weird. Marked near the hinge "(c) Matisse".
