Hi ,
Nice tumbler,I think what you have is a late 17th to early 18th century Bohemian tumbler , everything about it adds up to this , the clear roundels and archways ,the all over polished deep cut engraving,the style of the trees, boat, people etc all say this is what it is , I think it will be impossible to name the engraver though,there were so many and very very few ever signed there work so that comparisons can be made.some can be attributed to engravers who been given a name by the style and quality of the cutting, the Master of Kuola being one of them , still unknown by his real name but recognized by his style , this one is in a similar style but not quite good enough for him though . there are a few books were you can see other examples , the Krug Collection catalogues are 1 and also a book "European Glass from 1500 to 1800 by Klesse and Meyr, I have a few similar so will see what photos I have and pop a couple up later .
cheers ,
Peter.
