think the label should show silhouette of guy standing to the left, with the word KUMELA descending on the right, unerneath which is the word RIIHIMAKI - Made in Finland.
There's a selection of these Kumela 'fading colour' examples in Pina & Vigier, and what looks to be the same design of cylinder vase (in amethyst to clear) in Bill Geary's book - page 36, which is described as Riihimaki Vase - and that also carries a KUMELA label.
Unfortunately, your picture lacks sharpness and detail, so regret I can't be positive on that last comment - am sure we have Finnish experts here who will know.
Nice piece by the way.
