Krosno Poland blue glass controlled bubble vase bottle

Beautiful piece of glass from Krosno of Poland. It may have once been a decanter but if so, it is missing its stopper. It would make a fantastic vase. Cobalt blue glass with clear bottom and controlled bubble in the heavy base. Measures 7.5" tall. Has a few stray marks but no major defects noted. Original sticker is at the top. Smoke- and pet-free home.
