Vintage 70s Murano Sommerso empty pocket

Very beautiful and large vintage Murano empty pocket. Authentic Murano from the 70s. Cobalt blue and clear glass on the edge and the bottom, sommerso technique. No cracks, dents or other damage. Crazy modernist and timeless design. Bought on the lagoon in 1972 during my honeymoon. It has its label a little "cropped" because it has undergone a few washes, but it has the merit of being there and that is important. Magnificent object.
