This is a true Avem Murano block aquarium possibly 1950/60s. It is typical of the vintage block aquariums made during that era in Murano. The paperweight is in great condition with no chips or scratches. As pictured you can see bubbles in the glass, again typical of this kind of glass block aquarium. Well made and heavy, measuring 13 x 10 x 3cm.  Will be well packaged to ensure safe arrival.
