At the same time, with the exponential growth of urban space - the metropolis - and all its incongruities and inequalities, peripheral, underground, marginal art also appears. Graffiti and all its techniques and signatures spread across bridges, walls, poles and buildings, giving visibility to those forgotten by museums and auction houses. However, what is born as an alternative to the market is quickly absorbed by it: we see walls painted by Banksy being auctioned for millionaire figures.
In this sense, graffiti is legitimized as art from the sense of community that involves the participants of these movements. And in modernity, art is also defined as the mutual recognition between individuals linked by ideas, tastes and aesthetics.
