Poster décollage is an example of spontaneous, unplanned urban art that occurs during the removal of old advertising posters to make room for new ones or by natural process. This layering effect gives rise to unique and unrepeatable works of art. An “unconscious” art, because there is no human intention or intervention of an algorithm in this.

It is chance that teaches us to look beyond the surface of things and appreciate the beauty found everywhere around us, even in the most anonymous or unthinkable places.
