Murano turquoise blue glass trilobed empty pocket ashtray

Beautiful blown glass bowl in a wonderful, very bright turquoise blue color with an original trilobed shape. Originally I imagine it was an ashtray, but it would make a very nice empty pocket or simply a decorative bowl on a shelf, alone or in a collection. A beautiful craftsmanship that I assume is from the 60s or 70s, probably of italian origin, murano glass is very regularly cited for these trilobed bowls in colored glass, and this model is sometimes attributed to flavio poli but for my part I am not certain because it does not have a label. It is in good general condition, no cracks or chips but has rare signs of use: a few small, barely visible scratches. It also has small original "flaws": a few bubbles in the glass and a long mark (about 2 cm) on the glass on the outside, also barely visible. It measures about 16 cm from one lobe to another and a height of about 7 cm.
