Hi I agree with Jindra about this being an Emanuel beranek design. I also recall that I have seen evidence somewhere that Jindrich Beranek, after he left Skrdlovice for permanent living and glassmaking in Austria, may have made these vases in the 1970's for Lobmeyr Austria when he made a lot of hot worked designs for them. I do not know why he reproduced Emanuel's design. I have also seen this exact vase in different colours, signed in the same way by a J. Beranek, which is why I am not so convinced these vases with this signature are fake signatures.... I would expect different Skrldovice designs to be signed J. beranek (as fakes). My conclusion, without direct evidence to hand, is that it is possible that Jindrich Beranek produced and signed these in the 70's...
