graffitimundo : Street art for the people in Buenos Aires It’s only fitting, then, that graffitimundo, a company that gives graffiti tours in English, sheds light on the artists and their processes in an accessible way. Marina Charles, who leads the tours, doesn’t get bogged down with curatorial jargon that means nothing to the average viewer. She takes visitors through the history of the graffiti renaissance after the dictatorship, pointing out key art and artists off the beaten path from Chacarita to Villa Crespo and ending in Palermo.
