.5" by 1.5" exquisitely enameled double-faced copper plate with reproduction of Audubon blackbird magpies. Bale with 6 diamonds and petit pearl. Backplate is the negative, or underlayer of the original image, without the blackbird and coloration so that the 'skeleton' of the image is appreciated as its own art form. The frame is made of elaborate Mahlia symbols in gold with oval cabochon sapphires. (4-6 months delivery.)
