Early 70's Murano Art Glass 6-fish aquarium

I am sure most have you have seen one of these. I just thought I'd show you, as this one is pristine in every way. Again, it has been over ten years since I plucked this off eBay. I had bid on many before I won this one and lucked out and ended up getting for a lot less than I thought possible. I love to stare at it once in a while and just gaze at the workmanship of the Venetian Art Glass blower's and still wonder how they can do something, so detailed and so large! Having read about the family's in Murano that have passed down this fine art through the generations, it saddens me to see all the FAKE Chinese copy glass that is out there. I can tell, from experience, if it is real Murano to fake, most of the time. There are still moments when some Chinese, or other Venetian knock off artists, make it a challenge. But most of the time it is very obvious!
Very heavy!!!
