Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
A display device comprising: means having a reflective surface; half of a symmetrical object mounted on said reflective surface, said reflective surface being in the plane of symmetry of said symmetrical object so that when said half of the object is viewed together with reflections of said half from said reflective surface two symmetrical halves of said object may be seen simultaneously; said means having a reflective surface comprises a block of transparent material, said reflective surface being on the backside of said block, said reflective surface being viewed from the front side of said block and through the thickness of said block; said half of said symmetrical object being in direct contact with said block of transparent material so that said contact is free of an air space between half of said object and said block, said block applying refractions to reflections from said half of said object and from said reflective surface so that a predetermined view is obtained dependent on the direction from which said half of said object is viewed; said predetermined view in size and shape being also dependent on the shape of said block of transparent material, said block having a back side and a front side, said back side being inclined at a substantial angle with respect to the front side of said block.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
A display device as defined in claim 1 wherein said block of transparent material comprises a rectangular-shaped block.
Claim 4
Dependent Claim
31 words
A display device as defined in claim 1 wherein said block of transparent material has a semi-cylindrical shape joined by a planar surface, said reflective surface being on said planar surface.
Claim 5
Dependent Claim
19 words
A display device as defined in claim 1 wherein said half of the object is cut in said block.
Claim 6
Dependent Claim
19 words
A display device as defined in claim 1 wherein said half of the object is embedded in said block.
Claim 7
Dependent Claim
15 words
A display device as defined in claim 1 wherein said block is comprised of glass.
Claim 8
Dependent Claim
15 words
A display device as defined in claim 1 wherein said block is comprised of plastics.
Claim 9
Dependent Claim
194 words
A display method comprising the steps of: inserting into a block of transparent material the surface characteristics of half of a symmetrical object; applying a reflective surface to one side of said block of transparent material, said reflective surface being in the plane of symmetry of said symmetrical object; and viewing said surface characteristics of said half of said symmetrical object in combination with said reflective surface to obtain a view of said half of said object together with the view of the reflections of said half from said reflective surface so that two symmetrical halves of said object may be seen simultaneously; said half of said symmetrical object being in direct contact with said block of transparent material so that said contact is free of an air space between said half of said object and said block, said block applying refractions to reflections from said half of said object and from said reflective surface so that a predetermined view is obtained dependent on the direction from which said half of said object is viewed, said predetermined view in size and shape being also dependent on the shape of said block of transparent material.
