Most of us know Schubert but the second word gives me some hard time. Uh..must be a German word, and I was right.
It means
strong alcoholic beverage.
And that resolves this mystery of this statue. It is a wine bottle.
However, after opening the bottom, more interesting things came out.
It is a built-in music box in the bottom and also there is a small pin hole in the gap between the wine bottle bottom and music box top.
It might be for the spy purpose...lol...just a wild guess.
