ABSTRACT:
Apparatus for reflecting a message in a reflective surface and method of use. The apparatus comprises a substrate having message indicia thereon in reverse, mirror-image format. When the substrate is positioned on a surface adjacent to the reflective surface, the message will be reflected as a directly viewable image because of the mirror-image format, and the message will appear to "float" in the reflective surface because of the reverse format wherein the message is a light color on a darker background. In the preferred embodiment, the reflective surface is a vehicle windshield, and the substrate is positioned on a dash surface adjacent to the windshield such that the image may be viewed by a driver and/or passengers in the vehicle. A method of use of the apparatus is also disclosed.
