I have a beautiful and unusual glass vase - see photo. From my research I believe it Zelezny Brod by Miroslav Klinger, about 1950's but this I have deducted from the shape, quality etc. It is 22cm tall, 4.5cm across top and bottom and about 9cm at the widest point - it has 9 staggered pulled points arranged in three lots of three - it weighs about 1.3 kg. Can anyone help to confirm this or advise otherwise. many thanks
