World War I Trench Art Artillery Shell Casing Souvenir

This item is a large-caliber artillery shell casing, likely brass, that has been repurposed as a commemorative 'trench art' souvenir. It stands upright on its base, exhibiting a significant height and diameter consistent with heavy field artillery. The material displays a dark, aged olive-drab or brass patina with visible surface oxidation, scuffs, and minor abrasions throughout its cylindrical form. A central decorative element has been engraved into the metal, featuring a shield-shaped border containing the hand-stippled or engraved inscription 'SOUVENIR 1914-1918'. This inscription directly references the duration of World War I. The construction is heavy and industrial, showing the characteristic flanged rim at the base used for ejection from a cannon breech. The condition appears structurally sound but shows authentic signs of age, including a matte finish that has lost its original metallic luster. Trench art pieces like this were often crafted by soldiers or locals near the front lines using discarded military hardware. The craftsmanship is utilitarian yet deliberate, with the engraving serving as a personal or unit-level memento of the Great War. While no specific maker's marks are visible on the side, the base primer (not shown) would typically contain manufacturing stamps. The style is late-Art Nouveau to functional military commemorative, specifically dating from the immediate post-war period circa 1918-1920.
