  • Patent number: 4011676
    Abstract: A personalized message apparatus comprises a plate which has a cellular structure for providing fastening connector halves or holes. Integral with and covering the cellular structure is a surface which can be punched out in selected cells. The indicia comprises letters, numbers, fractions of letters or numbers, or other configurations or designs, each of which includes mating fastening connectors which fit through the punched surface into the holes. The indicia are placed over the surface and the connectors are pressed or snapped into the mating holes of the cellular structure. The plate, even without individual letters, numbers, fractions of these or the like, can be used for indicia by merely punching out or opening up holes in the proper arrangement to give the configuration of letters, figures, or any other shape or form.
