The billboard had been paid by the Miami-based Alianza Martiana organization on 37th Ave. and 4th St NW, exactly in front of the entrance to Casino de los Perros.
 

Alianza Martiana, named after Cuban national hero Jose Marti, emerged on January 28, 2001, on the day of Marti’s birth anniversary. The alliance is made up of Cuban-Americans and Latin-Americans. It has repeatedly spoken out for the release of Gerardo Hernandez, Ramon Labañino, Antonio Guerrero, Fernando Gonzalez and Rene Gonzalez —internationally known as the Cuban Five- in meetings held in different parts of the United States.

The organization has publicly denounced the biased trial to which the Cuban Five were submitted which condemned them to unfair sentences.

The Cuban Five were charged on alleged accusations of being a threat to the US national security when they were actually trying to stop Miami-based anti-Cuba groups from continuing to conduct terrorist crimes against the Cuban people.
