Marie,
These reminds me of some Finnish glass items I have seen on the Internet, but I cannot remember if they were by Nuutajärvi or other Finnish company. Saara Hopea or Nanny Still as posible designers also springs into my mind. However, I haven't 'googled' or tried to verify this in anyway - just something that joggled my memory (maybe wrongly so...).
Regards,
Tuija
