But looking at the age of those books (they look secondhand) and seeing that they're in Spanish, I really have to image that they were first read by beret wearing Uni students in the 60's, who probably passed them around clandestinely. They probably had reading and study groups that they didn't tell anyone about, and tried to set up underground newspapers. Maybe some of them tried to join a party, or even dreamed about their own revolution. Most probably went on to graduate and enter a liberal bourgeois profession, but maybe a radical few trained in a militia, or got arrested by a military dictator, only to get bailed out by their rich father, or, self exiled because they were marked as being subversive.
That time period must have felt almost magical with possibility in Latin America. Fidel and the Barbudos take over Cuba. The horrors of the Soviet Union and Maoist China aren't well known. It must have been so romantic to set up discussion groups in the back of bookstores, or in shady bars, stay out lake with your friends drinking wine or coffee, plotting the revolution.
Just reading about Che in Mexico before he met Fidel. The culture of cafes, intellectual discussion, literature and art, romance. I can't imagine a more interesting place or era to be a University Student.
