We have been buying and sell Czech glass for sometime now, this is the first pair I have seen. It has both a right and left point of view. Not rectangular or square but somewhat aysmetrical. Bohemia by Karl Palda. A stunning example of elegant and extremely delicate glass craftsmanship for which the Palda glass manufacture was famous for. It is made of hand blown etched crystal. Typical for this range of glass products is the combination of clear and matt satiated glass in which art deco patterns, the complexity of the glass geometry, using many pattern and style and mixing them to make every piece a unique modernist avant garde design. Condition: Excellent.
