Ever seen this? 

Fidel Castro set? 

The pieces are modeled after fighters from the Cuban army. During the Cold War, the Soviet Union and Cuba had a pleasent political disposition towards one another. Prior to what is known as the Cuban missile crisis, the Defense minister of the USSR, Rodian Yakolevich Malinovsky, visited the Cuban leader Fidel Castro to negotiate the placement of Soviet weapons and missiles in Cuba. Upon the conclusion of these negotiations, the Cuban leader gifted this chess set to General Malinovsky as a token of good faith.

King size 15.8cm. All four rooks engraved in Spanish by order of Fidel Castro, capturing the tensions between the US and Cuba/ USSR at the time.
