  • Patent number: 3983277
    Abstract: Improved placement apparatus comprises a compliant backer sheet, e.g., formed of foamed polyvinyl chloride, and a clear transparent overlay sheet, e.g., of vinyl, disposed over the backer and secured on three sides thereto, as by thermowelding, to fuse the contiguous backer and overlay plastic materials.A graphics sheet desired by a consumer, e.g., a wallpaper or fabric segment, is inserted between the backer and overlay, and enclosed by securing a flap-like member affixed to the overlay to the backer sheet. A double sided acrylic copolymer adhesive strip is advantageously utilized to secure the flap and backer sheet.
