This covered 1-1/2 quart baking dish or casserole is in the retro Country Festival pattern by Corning Ware. The colorful design with stylized blue birds and flowers was only produced for a short time between 1975 and 1976. The casserole is number A-1-1/2-B. It measures 7 inches square by 8-3/4" across the handles by just under 3 inches deep. It's in excellent vintage condition, clean with just a little minor rub wear on the bottom from use and storage, no design wear. The glass lid is spotlessly clean with a shallow, smooth flaked or fleabite on on corner.
