A 1974 art glass vase by Frantisek Peceny for Sklo Union (made by Hermanova Hut). The clear design is 'wax drip' and has two bands of large round bobbles, with vertical lines and smaller bobbles evenly spaced around, like melting wax or rain drops. Pattern no 20245/180 (180 is the height, 180mm). Clear and heavy moulded/pressed art glass vase with a typical Sklo baseline. A lovely design, a tactile op-art style retro piece, 1970s vintage.
18cm tall x 7.5cm widest (there are bigger and smaller version as well). Weighs 630g. 
Very good condition, I can't see any chips or flaws.
