Vintage 'tin' molds (all aluminum, made here in Wisconsin during the mid 20th century). The large heart is about 6 1/2" x 6 1/2", and the four smaller hearts measure about 3 1/4" x 3 1/2".
These are a little worn and shabby for baking or jello molds, but they made wonderful rustic style Valentine's day decorations, or as country primitive style hearts all year round.
