Hi I just found one on ebay listed as Vera Liskova, starting bid £9.99, I dont know much about Czech glass but I bought five of these from the Studio Cards/Webb Ivory catologue in 1987 for a party, they were if I remember 1.99 each (a princely sum back then) and I have two remaining. They still raise a smile when I use them and I am always on the look out for replacements...but not at a tenner!
