Wow...thank you for the fast reply! However, I'm not certain; are you familiar with the pattern or designer? I have a couple of pieces of old Orrefors (and some Kosta Boda vases) and they're different. These may be mid-century but I don't think the signature is Sven Palmquist's. If you could clarify with some further details it would be much appreciated!
Thanks, again for the really quick response!
