The Frank Lloyd Wright Luxfer Prism Wall Clock is based on his designed and patented series of forty-five prisms in clear glass tiles for the Luxfer Prism Company. Wright designed The Luxfer Prisms Office Building in Buffalo, New York, 1896-97, with the front and rear walls of the building made entirely of Luxfer Prism tiles. This clock incorporates two of the Luxfer Prism designs, including the flower design that was the only one that was ever actually produced. This clock includes a metal case in a bronze finish, raised hour markers on the dial, a protective convex glass lens and a quiet sweep second hand. Diameter: 14” Depth: 1.75”. From the Frank Lloyd Wright Collection by Bulova.
