A Piece of Art was a graphic mural consisted of a sequence of six ‘propositions’:

1. Malevich’s Black Square is neither about black nor about a square.

2. Duchamp’s Fountain is neither about a fountain nor about a urinal.

3. Kosuth’s One and Three Chairs is not about chairs.

4. Magritte’s The Treachery of Images is not about a pipe.

5. Manzoni’s Artist’s Shit is neither about shit nor about canned goods.

6. As Malevich’s Black Square is neither about black nor about a square; Duchamp’s Fountain is neither about a fountain nor about a urinal; Kosuth’s One and Three Chairs is not about chairs; Magritte’s The Treachery of Images is not about a pipe; Manzoni’s Artist’s Shit is neither about shit nor about canned goods, a piece of art is never about anything.
