Yes, thank you Jindrich I had looked through your catalogue resources before I posted and although I could see a similar shape I could not match the colourway. Thanks for making the catalogues available I find them to be very useful for expanding my knowledge.
I suppose the shape is the important thing though and that not all colourways are represented in the catalogues. Thanks for your reply, I do really like the piece but I may sell it on to invest in other Czech pieces.
Saying that after I have owned anything for a week I find it very difficult to part with and it is a visually stunning piece of glass art.
