The Telegraph Museum of Mexico City is a public institution that is at the service of society to share and care for its cultural value. Repairing the lines is an action in the form of a donation letter of the book: Semblanza Trágica del Telégrafo y de los telegrafistas Nacionales so that the museum takes care and assumes in its hands the responsibility to preserve and make prevail the memory of the telegraphers, from their own voices, because memory is not only an act of remembrance, but also a demand for justice.
