Vintage German Souvenir Silver-Plated Chalice for Gelsenkirchen

This item is a small vintage souvenir chalice or goblet, likely constructed from a base metal like brass or copper and finished with a silver-plated or nickel plating. It features a tapered, tulip-shaped bowl supported by a slender stem that flares into a circular footed base. The most distinguishing features are the decorative enamel crests applied to the front surface. One crest is a shield shape featuring the word 'KÖLN' (Cologne) at the top, though interestingly, the metal engraving directly above the crests reads 'GELSENKIRCHEN'. Next to this is a secondary octagonal crest with a red and white radial pattern reminiscent of traditional German municipal symbology. The tarnished exterior suggests a vintage age, likely mid-20th century (circa 1950s-1970s), which was a popular era for such European traveler commemorative-ware. The surface shows a significant amount of patina, oxidation, and minor scuffing, consistent with age and handling. The enameling on the crests appears largely intact with vibrant red, blue, and white colors still visible. The craftsmanship is industrial-grade souvenir quality, common for gift shop items during the post-war tourism boom in West Germany.
