ABSTRACT:
An apparatus designed for the purpose of viewing transparencies on an overhead projector is disclosed. The apparatus incorporates a frame and the transparencies are retained by a portion of the frame defining a mounting member. Substantially all of the weight of the frame is concentrated in the mounting member and a member in opposed, spaced relationship to the mounting member. Tabs extending from the mounting member into the area circumscribed by the frame, in which area the transparencies are positioned for storage and display, serve to retain the transparencies in relative alignment.
