Thanks, Robert and John!
I had thought that there should be not much doubt about the ID of this one, but who knows

Not a very common piece of Czech glass, I guess...
Usually I'm not so fond of engraved pieces either (I am always very disappointed when I see beautiful ZBS vases engraved with some stupid flowers or egrets), but I do like the subject in this one, and the fact that it is not just decoration but more part of the design.
BTW, the pic against the plain white background doesn't do it justice -- the colour gradient is more delicate in real nature...
