This one is puzzling me...
Stands a little over 27 cm tall, base is flat and polished, with bevelled edge and a smooth curve to the sides like in my other Skrdlovice/Beranek pieces from that period.
It looks quite similar to the Jan Beranek pattern 8044/28 (apart from the blue and yellow swirls at the top, and the airbubbles in the base).
I had a good search through Skrdlovice and Beranek catalogues and website, but nothing.
So I looked at more contemporary makers producing glass in this style like AGS Svoboda, Princ, Glass Atelier Beranek Jiri, to no avail.
I am convinced it has to be Czech, though.
BTW, this is already the second one of these I have seen...
Any help highly appreciated!
