This, I believe is an old letter press printing matte. This matte was secured in a form and molten lead was poured into the form. When cooled the solid lead block with the reverse image from the matte was placed in a form for printing. The reverse of the matte would then appear on the printed piece. Probably used in a newspaper. Very common in the pre-fifties
