This gorgeous art glass vase was produced in 1977 by Vandermark. It is signed Vandermark, dated, and initialed by the artist, Douglas Merritt, on the base.
The vase is done in a light blue glass with a russet feathered pattern. It stands 11" tall The trumpet area (or fan) is 9" across. There two minute and insignificant pinprick nicks on the bottom of the base and a small area next to it that is rough to touch. None is readily visible. I mention them only for accuracy. I could not get them to show up in a photo, they are that small.
