Small Sommerso Murano vase 1960'

Small sommerso vase (height 15 cm) in Murano glass; "immersed" technique consisting of blowing successive layers of glass; here inclusion of a turquoise blue tube / test tube vase, lined with a slight blue halo, blown into a straight parallelepiped shape in colorless glass; attributed to Flavio Poli. Very good condition, 3 microscopic defects, which can be felt with the finger but almost invisible to the naked eye (and difficult to see in the photos)
