"Raise economic efficiency to the maximum", cuban poster.

I bought this poster from a Cuban political exile in Madrid who was selling Cuban communist stuff.This is a very rare poster which is link with Cuban industry which is quite rare because the topic is not an OSPAAL poster (The Organization of Solidarity with the People of Asia, Europe, Africa and Latin America) or is a film poster.
 
Title: "Raise economic efficiency to the maximum" About Cuban economy: the economy of Cuba is a largely planned economy dominated by state-run enterprises. The government of Cuba owns and operates most industries and most of the labour force is employed by the state.
