Pilsner Glasses with Art Glass Detail in Base

This is a tall Pilsner glass with a glass swirl in the base. The bottom 3+ inches is solids with this small glass detail. I have ten of these glasses. I have not found any markings on them yet. Each glass measures 8 5/8 inches tall and is 2.25 inches wide. There are no chips, cracks, or other damage. See more at Debsellstoyou. Item: 24077 Location # 14/0
