摘要

An angular mirror for psycho-aesthetic vision, necessary for the studies of physiognomy in hairdressing, characterized by being constituted by a prismatic body of section in isosceles triangle of wide obtuse angle and on whose two angular sides there are disposed suitable specular surfaces, which will reflect the image of each of the facial halves, differentiating them at the same time.
