Graffiti is more than a visual experience, it is also a temporal and spatial experience (Lynn and Lea, 2005). There is a set of conditions (location, moment, social influence, political and cultural events, personal events, etc.) that coincide in a moment in time and that define what the artistic piece will transmit to the viewer. art, public and ephemeral. Here is a good example of a city that documents its works of art on changing walls.
