I like this one Anne.
Love the colour and the ribbing, it is a bamboo form vase, has two knuckles, it's like the reverse of the smooth Aseda with the smallest section at the bottom working up to the longest at the top.
It is interesting not being cased, that gives a better chance of attribution as Aseda and a lot of other 60s companies cased the bamboo vase.
Btw how high is it, and is the ribbing like panels?
It is turning out to be like the Fazzoletto, so many types and makers; I think that is what fascinates Ivo (and me)
