Brutalist Style. Uncommon early shape. Fantastic patina. Wonderful sound. I bought this early piece at the Arcosanti foundry of Paolo Solari in Paradise Valley, Arizona in 1977. It is a sand-cast bronze bell, clapper, and hanging bar with his signature copper "fin" shaped windcatcher. All the parts are original, except for the internal chain between the clapper and the bell, which was replaced with a new Cosanti chain. It has a verdigris patina that has been enhanced from being exposed to a Northern California seaside environment.
