Two portrait with person (between Franco and Francesco)
White bronze, person;
A person seats on a white bronze sculpture stool. The years this person is old represents the age difference in the couple who owns the stool. As the two protagonists of the portrait are alive the person seated in the stool must change because he must always keep the same age. When one of them will die the age of the performer will change: increasing if the younger person will die or decreasing if the older will die first. When the two owners will die, the age of the performer will be definetly fixed.
