"Rare Antique Pitcher Jug From The 19th Century In Blown Glass"
I would truly define the complexity of this blown glass jug as extraordinary. I have conducted extensive research without being able to find similar or identical ones. I would date this piece to the second half of the 19th century. Regarding its origin, my judgment is divided between Italy and Germany. If someone can better identify this object, I would be grateful if they would let me know.
