Circa 1938-1942: The Fiesta Kitchen Kraft bowls and lids were originally sold individually so that consumers could mix and match colors to their personal tastes, but an early 1940s promotional campaign featured a three bowl stack in yellow, cobalt, and original green coupled with a red lid. Refrigerator sets are not easy to find without chips, cracks, or repairs, and it is truly a great rarity to own a stacking set that includes all four pieces with their original black and gold Fiesta Kitchen Kraft foil labels.
