Stunning looking decanter! I was thinking Hoffman...maybe Desna...but can't find anything online and my books are all packed up.
I think a base shot would be useful, also dimensions.
We might be able to give you an idea of the age of this decanter, but most people shy away from giving valuations as they are dependent on so many variables.
Hopefully someone will be able to ID this for you...it's lovely. :mrgreen:
