It's a silver-plated ice bucket, likely from the Mid-Century Modern period (around the 1950s-1960s), featuring a distinctive pineapple-shaped finial on the lid and often includes a white bakelite insert for insulation. Primarily used for chilling and serving ice, and sometimes champagne or other beverages. The pineapple finial and silver-plated finish give it a classic, elegant, and somewhat tropical or festive aesthetic.
