Circa 1967-1969: Selected as a grocery store premium, the dark brown glaze was chosen for use along with an applied black decoration on the flatware pieces. The underglaze design gave the original vintage fiesta shapes a new look and helped modernize the line with contemporary motif patterns. Collectors of vintage fiesta will recognize the 10" dinner plate with its band of concentric rings, front and back. This example is in excellent condition with a bold and well defined underglaze decal and is marked "Sheffield TM Amberstone MADE IN USA". Measures 10 1/8" x 1".
