ABSTRACT:
The invention is a reflective sign of polymeric material. The base of the sign consists of a spherical mirror. The cover for the sign consists of a transparent spherical section suitable for mating to the spherical mirror. A first opaque visible emblem is applied to the convex side of the cover, and a second emblem is applied to the concave side of the cover, directly behind the first emblem. The second emblem is printed in reverse, so that when it is reflected by the spherical mirror, it appears to the observer in proper orientation. The combined first emblem and second emblem are, therefore, visible to an observer of the device.
