Michelangelo Pistoletto is considered one of the leading representatives of Arte Povera, one of the principal post-World War II artistic movements. His illy collection underlines above all the communicative aspect of contemporary art.
The six cups become a rotating sextet of "slices of a mirror", that reflect every thing or person that approaches them, thus becoming places for meeting and regrouping.
His work is exemplified by his artistic quest, based on art's ethical responsibility and its ability to communicate to people.
