Circa 1936-1938: The smallest bowl of them all, the number one, measuring merely 4 15/16"D x 3 9/16"H, finishes off the inside of the seven piece set. The vibrant red glaze is always a showstopper inside the bowl, and there is no better way to top it all off than by showcasing one with the early inside bottom rings. This example in the red glaze is in excellent condition with little to no wear and a few small skips on the base. It's nicely marked with a fresh crisp mold "fiesta HLCo USA 1" on the bottom.
