From one of Iroquois China's Mid-Century Industrial Designers; Ben Seibel, these cups and saucers are part of his Informal shape of dinnerware. The pattern of Gray and brownish Orange Leaves is known as Harvest Time. The design was manufactured between 1958 and 1969. In pristine condition there are no nicks, chips, cracks, or crazing on any of the pieces.
Lighting in some of the photos makes some of the cups appear to be lighter on the inside but all really are the same shade of "brown" (which is more like a dark pumpkin color.) The solid pumpkin color is found on the bottoms of the saucers and inside of the cups which accents the same color leaves within the design.
If a customer wishes to purchase these Cups & Saucers with the matching Plates, Sugar, Creamer, and Coffee Pot (Carafe) as shown in the last photo-- -they can all be purchased together for $145 (plus shipping) while they are all available.
