Fascinating Iittala Minerva art glass vase designed by Tapio Wirkkala - this is a shorter fatter version of this design and an excellent example. I think it's design no 2755. It has a ice/bark/ripple surface texture with square base and rounded simpler top. Art glass, Scandinavian, made in Finland. A 1976 design, so circa 1970s vintage. 
Excellent condition with no cracks or signs of age or wear. No maker's mark. No scratches, chips, flaws, nibbles, etc. Fantastic collectable example.
17cm x 10cm round top. Clear quality moulded glass (photos don't do it justice!).
Price includes P&P to the UK.
