Hi Ivo,
thank you for your suggestions!
The label on the ashtray looks authentic, is old and has a lot of wear...
I bought the piece on the fleamarket for little money about 10 years ago, so I doubt that someone placed it misguidingly (but who knows

)
Although there is very little information on SVCC on the web, I have seen some items with the same label , and to me they seemed of varying quality (one of them being a glass duck, I guess not Flavio Poli designed

)
You may certainly be right that the vase is Czech. It looks like some of the Pavel Hlava designs, just have not yet seen this one ...
edit: Thanks to your input I found this blue-green vase

And sorry about posting 2 items in one thread, I wasn't aware of the confusion this will bring for moderators...
Will not happen again!
Kind regards
Michael
