Sorry no pictures, but i saw a very similar Sommerso vase at an auction last week, it didnt have the
blue wings, but had a very similar 'architechural' shape, i have no doubts it came from the same factory,
and again, no doubt it was a good 40 or 50 years old, needed a lot of cleaning.
Estimate was 30-50, i left a bid of 80 and it sold for £120
