  • Patent number: 3997991
    Abstract: A display device for decorative or advertising purposes capable of apparently converting a black and white image into a partially or entirely colored image when visible light is passed through a pair of adjacent translucent sheets. The first sheet contains an image which appears from an observation point forward of the first sheet as a black and white image in the absence of the visible light passing through the first sheet. The second translucent sheet located closely adjacent the first sheet contains at least a portion of the image on the first sheet and is at least partially colored so that when light passes through the pair of sheets, a colored image which is the optical combination of said first image and said second image is apparent from the observation point. In a preferred embodiment, the black and white sheet is made from a paper having photographic properties and is photographically negative.
