This is a Fenton art glass Colonial Blue Hobnail pattern 3 toed egg shaped vase. It is 5" tall. The Fenton line number for this shape is 3653. It has a scalloped top that pinches in towards the center. The vase is in excellent condition with no chips or cracks. It is not marked, so it predates 1973 when Fenton began placing their embossed logo on all pieces.
