Acknowledgments
While writing this work, I have received inspiration and help from many people. For this, I am deeply grateful. I need to thank few scholars from very different disciplines, who helped me navigate the interdisciplinary difficulties of my project. I am particularly indebted to the precious advices of philosopher Andrea Borghini, who is a very generous listener and critic. I am also grateful to legal scholars Enrico Bonadio and Anjali Vats for their substantial help. My gratitude goes also to Dom Lopes, who encouraged me to write on street art, and to the enthusiastic researchers I met at the Urban Creativity Lisbon Conference. A special thought goes to curator Pietro Rivasi and graffiti writer Fra32. This work could not have been completed in the absence of their support. Fra32 also allowed me to use some of his glorious photographs. I also need to thank the editors of this journal and anonymous reviewers for their insightful comments and suggestions.
