Tell the art owner, and the press, that that is a beautiful sculpture.
You recognize the phallic representations.
You realize that they echo the open minds of the owners.
Get some porn stars to model with them in the background and publish the pics.
Go viral.
Proclaim the sculpture as worth ten million on the black market. Some south of the border invaders will take care of the removal.
This is not a bad idea ... be sure to include the address so others can enjoy the “artwork”.
