Blue cornflower Corningware Basic Cookwear, P-34-B4 quart Dutch Oven. There are a couple light marks on the bottom that I tried to catch in the pics. Includes a B-20 lid that fits though it is not the one listed as the lid for this Corningware piece. Will include a rack to set it on when hot. Measures: 12 1/4" x 11 1/2" x 3 3/4".
