Abstract

Half of two symmetrical portions of an object to be displayed, is cut or embedded in one surface of a block of transparent material. The surface of the block in which the symmetrical half of the object is cut or embedded, is made reflective, so that a person viewing the block of transparent material sees the cut or embedded half together with reflections of that half to obtain a view of the composite halves of the symmetrical object. The arrangement is such that when the profile part of a human portrait is cut or embedded in the block, a viewer will see the entire head of the portrait, and not only the profile part. The reflections providing the image of the other symmetrical half of the portrait which is not cut or embedded in the block.
