1950s Czech Art Glass Crystal Vase

Large decorative Czech art glass vase. A dramatic and striking case. The initials JB have been engraved onto the top right hand side of one side of the vase which are not a makers but a previous owners. Perhaps it was given as a gift in the past to someone with those initials.  Some small scratches to the base commensurate with its age and use.
