WOW! Rare find. Vintage 10 OZ blue glass tumblers with white artwork

These Six vintage ten ounce blue glass tumblers are for sure a rare find. The white etching on the outside shows a little girl and boy with their dog chasing butterflies. You can feel the artwork on the outside So so pretty. The bottoms have a marking on each of them. I ran them thru the dishwasher after use. But so pretty I would recommend hand wash. They were a special well preserved wedding gift to someone Approx 40 years ago
