1963/4 is the design date I have for this vase. I don't know the exact production period but this particular almost navyish / smoky blue colour would suggest early / mid 60s production.
A good web-site for Finnish glass is http://www.designlasi.com/en
—you can either just browse or search by maker / designer etc. You'll find other sites in Anne Yobunny's glass links resource: http://glasslinks.yobunny.org.uk/
There are books / exhibition catalogues specifically on most of Nuutajärvi's better known designers—Gunnel Nyman, Kaj Franck, Saara Hopea, Toikka, Heikki Orvola etc. and also a more general book, published 1993, Nuutajärvi, 200 Years of Finnish Glass
(out of print & difficult to find).
As for price, £8 is a bargain :clap: :mrgreen:
