A Picture A Day-Giulio Paolini

Giulio Paolini, The Other Figure (L'altura figura), 1984

 "The creative act is not performed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act." Marcel Duchamp
I saw this piece a few years ago at the Dallas Museum of Art.  It makes me smile wondering what these two aren't able to say out loud to each other.
