This fantastic folding piece by Evans Clark for Glenn of California can serve as a bookcase, a display shelf or a room divider. The mahogany case has five shelves on each side attached with a piano hinge. The shelves have channels on both sides for the sliding panels which can be arranged  in innumerable configurations. It’s a clever, versatile, and highly functional design with a very good build quality.
