" There is now a museum near Havana, commemorating the “Campaña Nacional de Alphabetization en Cuba” in La Ciudad Libertad or the “City of Liberty.” This museum is situated in Fulgencio Batista’s former office, in the western suburbs of Havana. The museum contains many thank-you letters that were sent to Fidel Castro with gratitude. These letters were also used by UNESCO to gauge the success of the 1961 literacy campaign. Many of these letters are now on display and can be seen along with photographs, taken around the island during that year. Additional materials including the records of all 100,000 volunteers are also proudly kept on file here. "
