Here's a very cool vase for sale! This is a 10" tall by 7 1/4" wide cobalt blue glass vase with a swirling pattern to it, fused to a 4-petal glass footing. This is most likely a one-off vase, produced and signed by David McDermott, a Sagamore, MA-based glass artist.
But this vase was made while he was still working for Pairpoint Glass in the same city. It is in perfect condition, ready for prominent display! It has 3 marks on the underside of the footing that I found when going over it with a magnifying glass. One is the Pairpoint'P in a Diamond' hand-etched logo; another is'Xmas 91' and then the signature'David McDermott'.
