Ok, the last one for now

I have this green pitcher (I hope that is the right word). I got this as a gift as we are known as the people with the glass in the neighborhood

I saw a similar one offered quite expensive as Empoli Glass. What is your thought on that. Is there a way to be sure. I looked up and down with german google, but could not find more than one. Also I browsed through the forum's empoli posts I could find.
Is there a way to be sure or even find more insights?
