        DescriptionThe T-square is constituted of a long, unfinished wooden arm with clear, yellow plastic edges attached to a shorter, black-painted wooden end piece by four small, iron, flat-head screws. There is a hole in the free end of the long arm for hanging the T-square. The plastic edges are riddled with cracks and a few chunks have broken off. No inscriptions or marks.
