Abstract: The present invention provides a lamination-assisted method for preparing high quality plaques for the purposes of commemoration, commendation, information, or award, having the appearance and durability of metal plaques. This invention further provides a method which may be utilized for the preparation of acrylic block displays for commemoration, award, information, or commendation using lamination, whereby the impression is conveyed to an observer of an embedded image. In either case the text or graphic image, as imprinted on a carrier, is laminated to the display solid by using an adhesive film. An additional protective layer may then be laminated to the carrier.
