THESE ARE THREE OLD VINTAGE WHITE IRONSTONE SMALL THICK OVAL BOWLS OR PLATTERS WITH STAINS AND CRAZING
They are not all the same, and one is unmarked at the bottom and the other two are marked Maddock & Son, and I can't make out the other. There is minor staining, minor crazing, minor dirt and wear.
Measurements are about 6" by 4 1/4" by 1 1/2" tall each.
