The "artist" of our masterpiece was Harrods' Food Hall. We christened the work Take A Bite and discreetly put it on show in a room housing prints and objets d'art by modern sculptor Eduardo Paolozzi. Close by were works by two of the past century's greatest artists, Matisse and Picasso. After all, Take A Bite, by fictional artist Spence Marx, was a serious piece, a work that "empowered" the observer to eat from the display and "actively engage with the installation".
