La Casa Encendida is a social and cultural center in Madrid that hosts a variety of contemporary artistic presentations and educational activities.

The exposition Todas Las Cartas took place in La Casa Encendida during some weeks on September and October 2011. In this exhibition, all the letters where shown as audiovisual tapes to be able to make exchange in between various cinema directors.

To show this exchange, the guide is similar to the letters language, and stamped in a die in the middle to be able to divide in two each one of the guides, turning each half in a postal card each. For every author different typographies where used to reflect their own voices.
