Very nice OLD graniteware enamel 20 quart pot and lid, cobalt blue and white. This is made with side seam and separate bottom joined to the pot, not like modern seamless pieces. It's heavier, too - a quality piece, early 1900s vintage.
This measures 12" across the bottom of the pot, 13 1/2" across the rim. It's 9 1/2" deep, holds 20 quarts comfortably as a stockpot. It's water tight, but does show wear and soil from use.
