This vintage cobalt blue glass vase in a swirl pattern has no makers mark, but could possibly be made by the Hazel Atlas Glass Company. There is a story that the Hazel Atlas company had a large vat of cobalt blue glass left from making a planned quantity of Shirley Temple items, and decided to use it up by producing some of their other lines in cobalt blue. I will have to let the new owner decide. In very good + condition, without chips, cracks or fleabites it measures 7 1/2 inches tall, 4 inches across the rim, 5 inches wide and 3 1/2 inches across at the base. An addition to any Cobalt Blue Glass Collection. SH & Ins. will be quoted after orders placed. If you have any questions please contact me and thank you for looking.
