Thank you Pip, I would think that Mexican origins might be a better bet, the quality or 'clarity' of the glass would push my thinking in that direction. I have never had the good fortune to handle any of Wiktor Berndt's work so I have little to judge this vase against. I have only had it for a week or two but it is really growing on me, I do like it's naivety.
If any one out there has any of Berndt's Tribal designs it would be interesting to know of the clarity of the glass used.
