Hi ,
Sorry but i don't have the full answer but think I can point you in the right direction , the glass is almost certainly Bohemian 19thc , and I think you should look into the engravers Karl Pfohl and also the Pohl family , both these engravers were very fond of this subject type, i have seen a similar glass in 1 of my many books but so far cant find it ,My main interrest is in 17th and 18thc mainly English glass which is why I am little lacking in this dept the quality of the engraving looks very fine indeed and if can be attributed to 1 of the great engravers like Pfohl it could be a pretty valuable find ,
If i manage to find out anything more concrete I will post it ,
great find , Peter.
