The postcards, distributed at the Roissy-Charles de Gaulle airport by the Paris-based group are part of a campaign to raise tourists' awareness of repression in Cuba.
The cards were given only to people traveling to Cuba on Cubana de Aviación, the Cuban airline.
''This is not a call to boycott flights to Cuba, but just [a way of letting] those who go to that country know that behind its sun and beaches there is a totalitarian regime that represses and impedes freedom of the press,'' Reporters Without Borders Secretary General Robert Menard said.
The cards feature Argentine-Cuban guerrilla Che Guevara's face superimposed on an anonymous police officer, who in a famous image from France's May 1968 protests held a shield in one hand while brandishing a club in the other.
``Did you choose Cuba for its friendly people, its lovely beaches, its rum and its seductive rhythms? Know where you're heading. Behind its cliches, the sun doesn't shine for everyone.
' `Che' is no more than an icon used by the authorities to legitimize their repression,'' the back of the postcard reads. [End]
Seventy-four Cuban literacy experts were to train 100,000 Venezuelan teachers to give classes in reading and writing to 1.5 million Venezuelans -- nearly 9 percent of the population -- who are currently illiterate.
The Cuban participation is opposed by foes of leftist Chavez. They accuse him of ruling like a dictator and trying to replicate Communist-ruled Cuba in Venezuela, the world's No. 5 oil exporter.
In a video conference broadcast from Caracas to schools around the country, the Venezuelan leader praised the literacy program as a major advance in his so-called "revolution" to improve the lives of the country's poor.
"This has nothing to do with indoctrination," he said, dismissing allegations by opponents that the campaign would seek to impart Marxist ideology along with reading and writing skills.
The campaign, providing two hours of classes a day at teaching centers around the country, will be headed by Eliecer Otaiza, a Chavez loyalist and former chief of Venezuela's DISIP security police.
Chavez thanked his friend and political ally, Cuban President Fidel Castro for donating texts, videos and 50,000 television sets to help the Venezuelan literacy drive. The Venezuelan leader briefly visited Havana during the weekend for talks with Castro.
In a growing alliance that has irked the United States, the biggest buyer of Venezuelan oil, several hundred Cuban doctors, sports trainers and farming experts have been working in Venezuela under a bilateral cooperation treaty.
Venezuela also supplies up to 53,000 barrels per day (bpd) of oil to Cuba on preferential terms, making the South American nation the Caribbean island's single biggest trading partner.
Chavez, who was first elected in 1998 and survived a coup last year, frequently praises Castro and Cuba but denies that he shares the Cuban leader's Communist convictions. [End]
