For enthusiasts only. The most demanding photography book from a technical/production point of view that the publishers have ever produced, using only materials of excellent quality. After dozens and dozens of failed attempts finally we have a photography book that the professionals, those who have attended the Institute and appreciate the value of prints, can appreciate to the full. This is not a book, it is a work of art. The publishers compliment the Pref. Esposito and the entire staff of the Istituto Superiore di Polizia, Liborio Capaldo, Fabio from Nuova Grafica and the Istituto Grafico Editoriale Romano.
