Murano Glass Aquarium by Francesco Ragazzi (Ferro) 2011 6 1/2 Lb's, 2.94835 Kg With 6 bright fish and surroundings. Registered VR sticker on lower left. It probably stands for Vetreria or Vetro something but I can't find anything. It doesn't make much sense as Ragazzi seems to work only for Ferro and it's not their label. It could be a retailer (but it's a registered trademark). Bottom with the masters signature, Murano and what looks like Venena, 2011 6 3/4” tall x 7 3/4” wide x 1 3/4” 6 1/2 Pounds When held to light and closely looked at there 2 places with short light scratches. last 2 pics. Not detracting from the piece.
