The Columbia Police Whistle is a small, metallic whistle with an Art Deco design, featuring sleek, geometric lines and a polished brass finish. It has a distinctive, elongated shape with a slightly curved mouthpiece and a loop at the top for attachment. The surface is smooth with minimal ornamentation, but includes small, engraved details that reflect the steampunk aesthetic, such as tiny gears and cogs etched into the metal.
