Hi ,
I have this Timo Sarpaneva bird bottle in purple which is not signed like others I have seen on line , The design shape is 2501 from i-glass Iittala yet mine is signed TIMO SARPANEVA IITTALA S'461 .
I've also found them simply signed "TS" , "T.Sarpaneva 2501" and also "Timo Sarpaneva Iittala -57"
There looks to be quite a difference in price between different sites and I was wondering if the way it is signed has any relevance to it's age or value , Many thanks for any help , Dave.
