This is a mid-century refrigerator water box (or butter/leftover keeper) made for Norge refrigerators. "Hydrovoir" refers to the water storage unit that was part of the Norge refrigerator’s humidity-control feature. Enamelware from vintage appliances, especially branded pieces, is collectible due to nostalgia and durable construction. Its value is enhanced by the visible branding and decent condition (light rust and wear typical).
