    Abstract: The present improved display device permits the improved viewing of such specimens as transparent films, both negatives and positives, translucent objects, such as drawings and water-color prints, selected minerals, and opaque objects smaller than the viewing plate of the device.The device is inexpensive to make and use and operates economically on a low wattage light source. The device includes an open topped box with a light, such as a low wattage electric light, therein. To the top of the box is affixed a translucent display sheet, while a frame which is preferably glassed in, is hingedly connected to overlie the display sheet so that speciments can be easily placed on and removed from the display sheet.The distance and angle between the light and the display sheet preferably can be varied so as to provide different display effects. In one embodiment, the light is secured at a distance from the center on the box bottom and the sidewalls with attached display sheet are rotated relative thereto.
