This chapter analyzes Cultura Obrera (Labor Culture), published in New York City from 1911 to 1927. Pedro Esteve, the primary editor, gave expression to his ideas in this newspaper and while it represented Spanish firemen and marine workers, it reported on many other workers’ struggles in different parts of the world, for example, supporting and collecting funds for the Mexican revolutionary brothers Flores Magón. This newspaper, as all the anarchist press, was part of a transnational network and had a circulation not only in many parts of the United States but also in Latin American countries, including Argentina and Cuba, as well as on the other side of the Atlantic, in Spain and various European countries.
