Transparency display apparatus is disclosed including a transparency storage device for protecting transparencies during transport and for facilitating display of transparencies upon an overhead projector and a staging assembly mountable on the stage of an overhead projector and cooperating with the storage device for transparency display. The storage device is separable from the staging assembly during transport of the transparencies and is constructed in a manner which fully protects the transparencies by providing covers and sides which form a package for holding the transparencies. When utilized for displaying transparencies, the storage device may be opened up and the covers pivoted out of place into a position where they support transparencies before and after display. The staging assembly includes fastener means which cooperate with fasteners on the storage device so that the storage device is supported while the transparencies are being displayed. The staging assembly has a transparent panel positioned above a light source and relative to the storage device so that transparencies carried in the storage device can be pivoted about their point of attachment to the storage device for selective display over the transparent panel on the overhead projector. The staging assembly also includes supports adjacent the transparent panel for supporting the covers of the storage device in a position where transparencies can be collected and disposed upon one of them before and after display. Individual transparencies retained in the apparatus may be moved about an axis lying in the plane of the transparency as well as about an axis intersecting the plane of the transparency, generally one perpendicular thereto.
