  • Patent number: 5822895
    Abstract: A visual memorial system for a long term display of an archival print. A pigment-based print generated from a photograph is matted and placed within a resilient frame which is covered with tempered glass opaque to ultraviolet light. The frame is placed within a stainless steel casing which is attached to a gravestone by anchor bolts. The frame is preferably provided on its interior with a desiccant to remove any remaining moisture from the interior of the frame. The archival nature of the pigment-based print along with the sealing techniques used in the frame, produce a resulting memorial system capable of maintaining its clarity for over a century.
