Collection of political posters mainly focused on the years of late Franco’s regime, the Spanish Transition (1975-1979) and first democratic elections. The collection, based on Josep Vinyal’s donation, belongs to the Documentation Centre on Communication (CEDOC), attached to the Communication and General Newspapers Library of the Universitat Autònoma de Barcelona. The posters reflect the political activity in the above mentioned periods: election campaigns at local, autonomous, state and European level as well as political parties and trade unions propaganda. There is also a remarkable set of posters from different countries worldwide such as Italy, Chile, France, Portugal, Greece and the Soviet Union.
