Décennie infâme
Pablo Mastandrea (11 February 1906 – 29 November 1976), an anarchist, worked in Haynes Publishing for decades as a typesetter, along with Don Emilio Mulli. Both were militant union delegates who stood up for the rights of the workers during the Infamous Decade (1930–1943). This period was characterized by electoral fraud, persecution of the political opposition (mainly against the UCR), and generalised government corruption, against the background of the Great Depression.
