摘要

A double vision medallion characterized by the fact of constituting a plate (1) preferably made of transparent plastic material, whose front face or face (2) is grooved forming a succession of parallel strips of little and equal width and convex surface, being greater than the magnitude of the relief, determining on the back of said plate, a cavity (3) with a smooth bottom in which a sheet (4) that is retained and covered by another plate (5) is accommodated. to the cavity (3) referred to, wherein the characteristic circumstance of existing printed on said sheet (4) is given, two different reasons, both configured by parallel equidistant lines whose separation from each other is identical to the width of the grooves of the face in front (2), the parallel lines of one drawing being displaced with respect to those of the other in magnitude exactly equal to half the width of said grooves, which lines s, when the sheet (4) is placed in the cavity (3) in which it adapts, they are placed exactly parallel to the grooves in turn.
