Unopened Vintage Corning Ware Blue Cornflower Casserole Dish 3 Quart A-3 Rare For Sale

New but definitely very old stock. Box has never been opened but box has some wear from being stored over 60 years. Cardboard sides are sealed shut.... as much as I would love to open it and see a brand new untouched corningware from the 60s... I held myself back! This was an estate find that was a wedding gift and she didn't like her mother in law whom gave it to her so she never opened it and put it in the attic to be forgotten about until today! Definitely a rare treasure! Will be shipped double boxed. I ship out next day!
