...or Maurizio Cattelan's?
A decade ago, the Bremen Totempole Animals were located in the square outside the Opera House. This was apparently part of celebrations for the 10th anniversary of German Reunification. Note the bicycle chain in the background, also part of the festivities. Germans are weird.
Now they are older and more settled in their ways, and they prefer to stay inside the Kunstmuseum.
So far the Bremen city fathers have not commissioned a plastinated version of the Totempole Animals from von Hagens, but it can only be a matter of time.
There are laws -- I don't know if anyone has studied them -- that determine which prominent part of a statue's anatomy tourists will choose to stroke for good luck, when it is erected in a public place.
Probably it is just as well that in this case the sculptor omitted the donkey's dick.
Bonus Maurizio Cattelan:
