The product is an extremely RARE VINTAGE Corning Ware A-1-B Spice of Life casserole with a square shape and multicolor design. This is a really unique piece! It has the number 15 on one side of the L’Echalote & a number 16 on the other side. I have not been able to find any out there that has two different numbers such as this one. It also has the 278MA stamp which is pretty rare in itself. This dish is in excellent condition and would make a great addition for any collectors set. It comes with a P-7-C lid. This mid-century modern piece is made of glass and ceramic materials, featuring a glossy finish. It is compatible with various oven types including induction, electric, gas, microwave, and steam ovens. The casserole has a capacity of 1QT and comes with a lid. This Collectible item from the 1979-85 production period is a decorative and functional addition to any kitchen collection.
