Nice old tinned steel milk or cream can with the remains of original Cream City paper label. I've never seen one of these old cans so nice before, never used at all.
It's right out of a farm estate here in Wisconsin (Cream City brand comes out of the Milwaukee area, this stayed close to home). It's made to hold around two gallons, measures 12 1/2" deep and straight sided shape is about 9" across the rim.
