Piece number 18 is a match for the beaker-vase I had - and I can see my goblet in the cabinet of glass above number 21!
The cabinet seems to be labelled thus;
"KNICEK GLASS
Knicek glass is quite distinctive. The PANDORA glass line, consisting of metalic reduction of enamels, was created by master enamel artist Maximilian Boudnik. it is quite difficult to find in this country."
my goblet has its Hortensja plastic label still on it.
To what country might the cabinet label refer when is is saying it is difficult to find?
