Thanks so much, Jindrich. With you around, I guess I don't need that many labels, and I certainly hope to learn much from you so I can start identifying by other means. And it's great that my vase is probably by Pravec. I like what I've seen of his not-too-ornate cut glass designs. Hope I can find a few more.
I might have another vase in my collection that would fit those ideas of relatively simple cutting. I've attached it to check if my way of thinking fits - can you see whether this could be by the same maker/factory? If not, I can make it into a seperate post.
I've tried to find out more about Josef Pravec - it seems he was active a long time, do you know if he mostly worked for Podebrady, or that he has worked for other factories as well?
The reason I still want to know about labels as much as possible is that for a beginner like me, sometimes they do narrow down the search a bit, if they were mostly used in a certain period (even if that was a 20 year stretch), and mostly in a certain area or by a certain factory. Do you know whether this particular label was used by more factories than Podebrady? And I guess the time period could be anywhere from 1950 to 1993?
