This is a vintage Corning Ware A-3-B 3-quart casserole dish featuring the popular L’Echalote La Marjolaine pattern—a colorful French herb and vegetable motif from Corning’s Spice of Life series. Made in the USA, this piece is designed for both baking and microwave use. The matching clear glass lid (model A-9-C) fits securely and is free of flaws. The interior cook surface is clean, while bottom of the dish shows wear from contact (see photos).
