Nice sommerso vase, purple-blue, clear cased. Rectangular shape, ribbed with scalloped rim.
Stands a little over 21 cm tall, flat polished base.
The design looks very similar to the "Sommerso a Coste" pieces designed by Flavio Poli in the late 1950s
>> LinkThere are even some bucket-shaped vases pictured in Heiremans' book, Selective Modellist 1960, page 151.
But these have a more massive base; and I am not sure if the colourway would be one that Seguso Vd'A used.
So probably Archimede Seguso?
Or generic maker?
Thanks,
