This free-form art glass vase measures 6 1/4" tall and 4 1/4". The sides of the vase are smooth. The photos look like there is a design. This is a light reflection of the fluted base create the design. The pontil on the bottom is polished. There are numbers and a signature. Even though the mark is very difficult to read, I believe it to be Orrefors, the Swedish quality art glass company. There is wear to the bottom. I would date this vase to the 1950's. The vase is in excellent condition.
