Propaganda fills the space that consumerism leaves on this Havana street (a famously ubiquitous sight across the nation.) A sign for the Young Communist League (Unión de Jóvenes Comunistas,) reading "Everything for the Revolution," stretches across a billboard next to the organization's motto "Estudio, Trabajo, Fusil" ("Study, Work, Rifle,") and the likes of Cuban revolutionaries Julio Antonio Mella, Che Guevara and Camilo Cienfuegos. While the organization's membership is voluntary (and selective - based on a clean record of pro-government views,) it is highly encouraged for social and professional success.
