Rare Controlled Bubble Blown Art Glass Small Cup Tumbler Vase Clear

A beautiful vintage art glass tumbler with controlled bubble design. Heavy and thick glass. No maker's mark. Measures 4" tall and 2¾" across the top. Gentle preloved condition. Surface scratches (hard to see and was unable to get them to show up in the close ups) but no chips, cracks, or repairs. Bundle with other items from my closet for discounts and combined shipping. Questions and offers are welcomed ☺
