You have a very nice weight there. I can't help but notice it has that real old look to it. Personally if I had $12,000 or so to plunk down for a Clichy etc it would be one of this type, with this bonified, no matter what someone says, old look. There is too many perfectly clear, no bubbles at all "perfect" ones on the market for all to possibly be real (original from France 1800's), from my personal observation, when most are known to be in private collections. I just can't get around that FACT either.
