Here is another of my vases that I love but that give me a headache. I like the amber glass, form and structure. BUT: The lady at the antique market could not tell me who the maker was. So I asked in a group on Facebook for help.
Two suggestions:
1. Japanese
2. Vladislav Urban for Rosice Czech 1969, pattern number 1506
Both I could not verify. As they always seem to be quite different. For instance: The Rosice's bottom is as wide as the rim. And the surface seems to be different. Also the rim has been evenly polished whereas mine is uneven (which looks very nice, I think).
So I leave it here in the hope of being identified someday
Hope the photos are clear enough.
