This rare item dates to the early 1980's and has the WG mark on the base, it is the Westmoreland Glass Product. This is the blue Opal/opalescent glass with the iridescent Carnival finish on the surface. This measures 11" tall and is 7" at the widest. There are no damages... but a couple manufacturing flaws-there is a slight bump at the edge of the handle, see photos and a straw mark in the manufacturing, I have shown photos of this line, but it is not a crack or damage. This item is rare, there are only 2 others known as far as I know of.
