VINTAGE CORNING WARE BLUE CORNFLOWER CASSEROLE DISH 1 3/4 Qt WITH RARE BLACK STAMP FROM THE 1960s. THIS DISH HAS ONE OF THE FIRST FEW YEARS OF STAMPS ON THE BOTTOM. I THINK ITS FROM AROUND 1966 PLEASE CHECK GOOGLE FOR EXACT INFORMATION. DISCONTINUED YEARS AGO AND IS VERY SOUGHT AFTER AND HARD TO FIND. DISH HAS BEEN STORED SAFELY FOR YEARS. PLEASE ASK ANY AND ALL QUESTIONS. PLEASE LOOK AT OUR OTHER ITEMS AND OTHER CORNING WARE. THANKS FOR LOOKING AND HAVE A NICE DAY!
