Small Cuff with Concentric Circles

Small Cuff with Concentric Circles by Alexander Calder. A green metal cuff with a wide, flat top and tapered bottom. The cuff features a series of concentric circles and horizontal lines etched into its surface. The cuff appears to have a rough texture. The cuff is sitting on a reflective surface with a beige wall in the background. The cuff casts a shadow on the wall behind it. The design on the cuff includes multiple sets of concentric circles. The concentric circles are made up of several grooves. The cuff's surface exhibits a green patina. The cuff's design and color suggest it is made from a metal such as copper or bronze.
