Functional Sculpture Three pieces. A freeform, 3/4-inch plate-glass top rests on two curved, solid wood legs that interlock to form a tripod for self-stabilizing support. The real thing. To assure authenticity, the signature of Isamu Noguchi discreetly appears on the edge of the top and on a medallion on the underside of the base; under the medallion, his initials are stamped into the base. Good size. 15 3/4 inches high, 50 inches wide, and 36 inches deep.
