Extremely rare green Quadrifoglia very large and heavy vase by Finland's Nanny Still for a 1967 exhibition in Belgium named'Duo Design'. It was based on a four-leafed clover. This vase was blown into a wooden mould lined with nails, it wasn't widely produced, thus this is extremely rare.
The orange version of this shape was more widely produced, but I believe this green was the original made for the Belgian 1967 exhibition, also made in black and purple. Weighing a heavy 5 kg and measures 20 x 20 cms. In lovely condition, a couple of small insignificant fleabites to the top rim don't really detract, they are only seen from directly above. Made for Finland's Riihimäen Lasi Oy.
