The French army museum in Paris is hosting an exhibition unveiling the history of 'Secret Wars'.

The fair is dating back to France's Second Empire until the fall of the Soviet Union in 1991.

It is unveiling the fantasized world of intelligence services and secret brokers.

Organizers say almost 400 objects and archives are on display including guides to sabotage, books teaching the art of disguise, tools used for espionage and code deciphering machines. The exhibition runs until January 29th.
