Lot of 8 glasses of wine or water - bubbling glass year 1970

Set of 8 foot glasses made of thick and bubbled glass. Can be used for water or wine. Bottle green glass - beautiful transparency. Each glass is unique because it was made by hand individually. One glass is much less bubbled than the others and one glass is smaller than the other. Irregular bubbles (a very long bubble on a glass) and a lot of bubbles that vary from glass to glass. No shrapnel, no cracks, no accidents. No signature visible but quite in the taste of biot. Date from the 1970s - so vintage and superbly decorative. Height 11.7 cm and 11.2 cm for the smallest. Opening diameter 6.5 cm for small and 6.7 cm for others.
