Imperial Glass Vintage Grape Pitcher and 5 Tumblers

This is a pitcher and 5 tumblers made by Imperial Glass. Each piece has the Imperial IG logo on the bottom. This carnival glass set is in the Vintage Grape pattern, but I'm not sure what to call the color. It is blue and purple in color with some gold highlights. I believe this set was made between 1951 and 1972. The pitcher measures 8 1/2" tall at the highest point and 7 5/8" from handle to spout. Each tumbler is 4" tall. The set is in very good condition with no chips or cracks. Please email me with any questions.
