Hi,
As modern as it comes, post 1992, in terms of date of manufacture, and the label is no great indicator, as it is used by both Sklarny Bohemia, Podebrady and Sklo Bohemia at Svetla nad Sazavou, from 1993 if it states Czech Republic (Czechoslovakia was used before that for three years at most). Very difficult to find a named designer for this item.
Regards,
Le Casson
