The book is a work of psychogeography, detailing a period in Debord's life when he was in the process of leaving the Lettrists, setting up Lettrism International.
The work contains two separate layers. The first is printed with black ink, reproducing found text and graphics taken from newspapers and magazines. The second layer is printed using coloured inks, splashed across the pages. These sometimes connect images and text, sometimes cover them, and sometimes are seemingly unconnected. The black layer contains fragments of text, maps of Paris and London, illustrations of siege warfare, cheap reproductions of old masters and questions such as 'How do you feel about the world at the moment, Sir?' The coloured layer contains freefloating ink splashes, lines created by a matchstick loaded in ink, and a Rorschach inkblob.
