 The annual event aims to recognize the talents of these “grafiteros” which the museum considers to be victims of marginalization.However, the event has been attended by officials from the city's Public Security agency, the borough of Coyoacán, technical schools and even the Cuban embassy.In 2009, the graffiti exhibition was sponsored by the city's Secretary of Public Safety and a snack food company with twenty works considered to be the most representative of a contest called “Las cosas chidas, rólalas” (Cool things, roll (share) them).
