Abstract
Abstract A portable transparent display device consists of two elements, viz. (1) a flexible transparent generally flat receiving element (e.g. disk-shaped), one face of which is recessed to form a receiving space, the side walls of the receiving element defining the receiving space slanting inwardly and upwardly from the bottom thereof; and (2) an insertable element, mating with and insertable into the aforesaid receiving space and removably locked into position by the inclined side walls defining the periphery of the receiving space of the receiving element. A thin paper insert or the like bearing a message or photograph, etc. may be clamped between the receiving element and the insertable element and the device used for display of the message or photograph, etc. through the transparent receiving element. The insertable element may be provided with a clasp at the rear surface for attaching the device to the clothing of the wearer.
