This abstract is resulting from a sociological visual research about the Tourism whose aim is to understand the changes and the permanent aspects of the local and territorial structure of a specific area of the Italian East Coast: the area of Cervia. Having at our disposal a postcards collection about this area covering the first 60 years of the past century, a specifical and new method of research has been used: re-photographing, many years later, the same places showed in the postcards. In this way, the abstract try to make clear the potentiality of this new original research tool.
