Zelezny Brod Sklo art glass BIRD by Miloslav Janku. Vintage 1960s ZBS. Green & amber sculpture. Minimalist Czech/Bohemian figurine, sommerso

To the best of my knowledge I believe this is a beautiful ZBS (Zelezny Brod Sklo) art glass bird figurine. Designed by Miloslav Janku and circa 1960s/1970s vintage. He's an aqua green colour (light green with a hint of blue), with a paler tail and beak and an amber/brown sommerso (floating colour) central core. Minimalist and simplified design, yet perfectly formed and recognisable. Skillfully made by an artist. I believe Janku made a series of simple elegant glass animals; this is the bird. And like many of the smaller figurines this one is unsigned.

Excellent condition with just a very slight slither fleebite along the baseline, impossible to see on display.
Please see photos. 7.7cm tall x 12cm long. Flat polished base. (The black dot on his tail came off after I took the photos!)

Includes P&P to the UK.
