Big heavy and flat 2-5/8" tall sheet of metal with muted silver luster has hand engraved Polish eagle to accompany part of the text also in Polish. Front reads "United Steamship Agency/326 E./14th St./N.Y./City/Z. Jednoczona/Polska/Instytucya." Nearly all the black accent paint remains on the recessed lettering. Reverse has large vertical pin held in place by a generous line of original solder. Likely from the early 1900s prior to our entry in World War I. NM.
