Why do Writing, Wall Painting and Street Art, artistic expressions that are now well established, remain subjects that are both much cited and much misunderstood? And how can six artists, Marcello Jori, Luigi Presicce, Simone Tosca, Cuoghi Corsello, Joys and Rusty be related together within an important and historic Biennale?

Six scholars from different scientific fields, called upon to delineate the socio-cultural impact of such artistic practices in the most disparate public places, seek to resolve these questions in this volume, which is at the same time an in-depth account of the proceedings of the Study Day entitled Do The Right Wall/Fai il Muro Giusto and a detailed report of the XXII Biennale del Muro Dipinto.
