Wonderful Miniature English Copper Ring pattern picture frame ca. 1870-1880s. Measures approximately 2 3/4" x 3 1/2" overall; photo/glass area approximately 1 1/2" x 2 1/2". Thin cast, not stamped, copper rings show ample hand finishing. Convex inner border; original easel. Your photo slides in behind the glass. Warm patina. Sweet little frame a bit more unusual than the ring frames normally found in brass.
