Cuban poster art

Looking through books on my shelves I wanted include this as influence because I love they way they are designed. Cuban poster art from the 1960s through to the 1980s was heavily dominated in promoting various political/social themes and as a way to create national pride. They were specific to their audience, a semi literate country, were easily manufactured and distributed and encouraged the arts. They have had an influence purely in the way they look: colour, composition, type etc but they also interest me because on the one hand it could be argued that they act in the same way as JMB child safety posters as a social tool or it could be that they are opposite by using manipulative means to control a nation and divert thinking.
