Found this in my travels today:
I've seen bottles that look like this and the design is almost always a fish-This is the first snake I've seen.
The optical clarity of the bottle is sharp, and it appears to be a mass produced replica made using modern manufacturing techniques.
The odd thing is that there are air bubbles trapped in the glass, and when hit with short wave UV light it fluoresces green (manganese).
Nearly all replicas I've found don't use manganese...and most don't include air bubbles.
It is only marked with embossing 'F00 Morel' and 'Barcelona'.
I tried looking it up online, but couldn't find any info on it. The design is very similar to vintage/replica Italian wine bottles.
Anyhow, I though it was pretty neat: Cost me a hefty $6 USD.
