The proper term for your item is that it's a "logo cut," used in the letterpress printing process. Since it's mounted on a piece of wood (called furniture) that indicates that it was locked into a chase (metal frame) that held all the other type. Once all the furniture was arranged in the chase, lead low-base metal was filled in around the cut (Content of the ad). Once completely locked, the chase was put into a flat-cast rolling machine that used a pliable mat that incorporated the entire ad into a flat-cast lead plate. Depending on the type press used, if a newspaper, then the flat cast was then put into a page chase and the craftsman built the newspaper around the ad. If it was a hand letter press, the flat cast was buttoned in a smaller frame and a roller inked directly onto the cut or flat cast and printed directly onto the paper. Your etched cut could have been used on a matchbook cover or was one size logo used on a napkin or similar paper product. Offset printing replaced this process in the late 50s. Hope this helps.
