CorningWare Blue Cornflower casserole dish Rare Find

This vintage CorningWare casserole dish in the Blue Cornflower pattern is a rare find in the rectangular P4B shape. The glossy finish and blue floral theme add a touch of elegance to any kitchen. It includes a lid and is heat-resistant for versatile use. It was produced in 1970 and is an antique original piece. The set is a very rare shape it’s in very good condition in my opinion as you can see from the photographs if you have any questions please let me know
