This is an unusual Fenton "Silver Turquoise" candy dish/footed comport, manufactured from 1956 through mid-1959-- and delightfully 50's looking it is! An opaque blue-turquoise color, handmade and spun round with a ring of clear crystal on the edge. Because it was made for such a short time, this color is quite difficult to find. Fenton's ware number 7228 ST. The comport measures 7 inches across at its widest point. Simply beautiful!
The last picture is an excerpt from Fenton's 1959 catalog that shows this comport, along with two other items of the same color. Retro!
My inventory number is A54A.
