Imperial Glass Marigold Carnival Grape Pattern, Footed Sugar and Cream Set #831, Ca. 1962 - 1972.
I have not seen a nicer set than this one, ever. No damage or flaws. It is shiny, sparkly, clean as a pin and ready to go. Imperial Glass called their lovely Marigold color, Rubigold.
The open sugar is 4-3/8" tall X 5" wide from handle to handle and the opening is 2-3/4" ID. The creamer is 4-3/4" tall X 4-3/4" from spout to handle.
Both pieces bear the embossed IG mark with the superimposed I over the G. The marks are on the outside bottom.
