Gorgeous purple plum colored 10" Carnival Vase in the TREE TRUNK pattern from Northwood glass. It is signed with the famous Northwood "N" on the bottom. The piece is in perfect condition...no cracks or nicks to the flutes at the top, or anywhere else for that matter. The iridescence is superb and when held to the light reveals it's "inner beauty". This is a much richer purple than most of the books call amethyst so we are not sure if it is an amethyst variation, or a truly separate color. No matter, it is beautiful regardless of what it is called.
