As of June 2019, what is the most expensive sculpture ever?

Surely it's "as of 11 may 2015" and "as at June 2019"? That allows the question to remain correct even if another sculpture exceeds the sale price at a later date.

I just Googled the sculpture. It looks a lot like a long limbed stick man and doesn't strike me as an outstanding work of art. Perhaps to behold it with one's own eyes it is marvelous?

Google this one...a bronze stick figure! I prefer classical Greek or a Degas dancer.
