Jindrich, I respect your expertise as always - but I'm still trying to get a better feel for where this vase belongs...
I do observe that some of the design elements that are used in this vase seem to be present in the links you've provided. The Beranek and the Princ catalogues for instance have semi-cylindrical style vases that are round on opposite sides, and cut flat on the other opposite sides like this one. Some of these have small round lenses cut out. And the colours blank and blue are commonly used in these type of vases. Other elements, like the semi transparant layer, seems to be missing.
It may not be Czech, as you say, but other than perhaps German the Czech style elements fit more closely than any other region I could think of - unless it's an attempt by a modern factory (China perhaps?) to produce something Czech-like in this style. My questions: has anyone seen non-Czech factories anywhere anytime use these kind of style elements? I know the Chinese copy a lot of Murano elements, and Ikea likes to borrow Scandinavian design elements - but have they tried Czech elements as well?
