Abstract
A device for mounting a transparency. The device includes back and front sheets of transparent plastic. The outer edges of the sheets are continuously bonded together. In a preferred embodiment, an opaque coating on the front sheet defines one or more generally rectangular windows. Each window is variously sized to permit the transparency to be viewed therethrough but to prevent light from leaking around the transparency. The sheets are continuously bonded together along three sides of the window to form a pocket between the sheets for mounting the transparency. A slit is formed along a fourth side of the window for inserting the transparency into the pocket.
