ABSTRACT:
A display device is formed of thin plastic sheet material extending about a peripheral frame. The frame is formed of a relatively stiff annular core element encapsulated within a resilient foam sheath or shell. In attaching the plastic sheet to the annular frame, edge areas of the sheet are wrapped about the surface of the rubber shell so that the shell is deformed inwardly toward the frame central axis, whereby the deformed shell exerts outward force on the plastic sheet to prevent or remove wrinkling of the sheet. The display device may be suspended, as from a cord or a button on a garment of a person.
