For the homeless, cardboard boxes are a strong ally, as they are one of the few channels through which they can seek empathy from passers-by. But the cardboard with the inscription is not aesthetically attractive, even if it has graceful marks of the felt-tip pen. The range of the message is thus severely limited. But nothing more, because it was the font of the "Kings of the streets" of Barcelona that was the basis for the charity project of the Arrels Foundation and The Cyranos McCann agency, which turned the five into fonts.
