  • Patent number: 3962836
    Abstract: A grave marker for permanent mounting in a concrete slab poured around the marker. The marker has a pan-shaped cover constructed of rigid transparent, vacuum formable or pressable acrylic and defined by a flat center-portion and sides depending transversely therefrom. A flat base is hermetically sealed to the sides, parallel to and spaced from the center-portion of the cover. The inscription for the marker is formed on the side of the base facing the center-portion by bonding individual symbols, e.g., letters to the base or by bonding to the cover or the base a thin, flexible plastic sheet having raised letters thereon and positioned so that the letters are spaced from the cover. A coloring agent is applied to the inscription and interior marker surfaces visible through the center portion of the cover to simulate relatively expensive substances, such as bronze, brass, silver and the like while the marker is constructed of low cost materials.
