Vintage abstract wooden sculpture is titled Bent Triangle. Signed by Reid and dated 1976 Robert Reid? Good used condition, any reference to the size and condition in the attached photos. Characteristics of the Opera. The work has a complex geometric shape that recalls a “folded” or distorted triangle, made with a woodworking technique that highlights the grain and natural shades of the material. It rests on a base composed of several overlapping wooden discs, which gives stability and an additional sculptural element to the composition.
