Fenton Art Glass is quite collectible. You did well for ten dollars. My WAG is at least ten apiece for unsigned and double that for signed. The Aqua Blue bud vase on top is very nice! Any signatures on the bottom?
There is a Fenton Art Glass collectables club with their national HQ in West Virginia.
