Not many of these probably survived...it's a styrofoam exterior over what I think is a metal enameled interior core, holding about 1 gallon. The simple metal base helps protect it, and the original cup was still present under the lid. What a cutie! The spaghetti painted finish is a great period look for your canned ham, circa 1960s. While showing signs of age, e.g. cracking in the styrofoam exterior and dents all around, it's got a great patina and glamping look that, with care, can be used but might be more fun for display. The top is an early hard plastic.
