This is a vintage white milk glass trumpet shaped vase with a slightly ruffled top and a set of concentric rings or ribs around the center. The vase is 7 3/8" tall and 4 3/8" wide. It is in excellent condition with no chips or cracks. The vase is not signed or marked, but I think it is most likely Anchor Hocking.
