    Abstract: A multiple static image display that can be used as a large sign in public areas, such as airports and shopping malls that present the images with a relatively short or non existing transitional period. The sign includes a light box with a plurality of light bulbs mounted therein. Located in front of the light bulbs is a moving, transparent image panel with a transparent image film temporarily mounted thereon. Formed on the image film are at least two offset images. Located in front of the image panel is a fixed screening panel that includes a checkerboard-like mesh surface made up of a plurality of clear, transparent squares or holes evenly spaces apart thereon within a black, opaque background. The images on the image film are offset a distance slightly greater than ½ the distance of the black dot. When the image panel is moved approximately ½ black dot distance different images can be seen when viewing the display from the front.
