The license plate is the element that from the very beginning identifies a particular vehicle and only that, almost as if it were its “identity card”, the element that distinguishes it from all other similar, but different precisely because of the license plate. With this book, Mino Faralli and Guglielmo Evangelista guide us on a journey to discover the meaning of the plates, from their origins to the evolution they have undergone over the years, illustrating the modifications and changes they have undergone. It is through the plate of a vehicle that we can retrace its history, know where it was registered, where it was used and who its owners were: a series of fundamental and indispensable data for any collector and enthusiast of historic vehicles. The 368 pages of the book written by Evangelista and Faralli become a sort of manual that integrates with the history of motorization itself. The plate is not seen only as a fiscal instrument, but is inserted in the various economic, social and political moments of the nation. The plates retrace the changes in the administrative systems, which lead us to discover what happened in some autonomous regions at a certain period of their history.
