I believe it's Erkki Vesanto for Iittala
This is hard for me to say, but: personally I wouldn't count on it just like that, but it's only me thinking if I should buy it as Erkki Vesanto.
I am very much looking forward, anyway, to second opinions,
as what I have seen in the kind of Iittala have been what I think is high quality at least in symmetry and what I see in that picture is a little squint here and there, or is it just my eyes? :huh:
