ABSTRACT:
A selectively transparent map system, for use by a driver in an automobile having an automobile windshield, comprising a map having map indicia printed thereupon. The map is selectively transparent so that when the map is held against the windshield in front of the driver, and the map is viewed at a first angle, the driver can read the map indicia while simultaneously watching the road by looking directly through the map. However, when the map is viewed at a second angle, the driver can read the map indicia, but cannot see through the map. The map thus includes a selective transparency means which preferably includes a grating having a plurality of blocking members which allow light and images to be easily transmitted through the map at the first angle, but substantially block light from being transmitted through the map at the second angle.
