Alberto Korda's photograph, which captures the essence of Che Guevara, hung for years in his studio before becoming the iconic image of the rebel fighter.

A vast version of the image, reduced to steel outlines, hangs in Havana's Revolution Square.

The image is so well-known that it can be modified and messed around with, while remaining instantly recognisable.
In many parts of Latin America - here, Venezuela - the image retains its political symbolism.
But even in Peru, a canny cigarette company has fashioned cigarettes with Che's image.
Its use on a bikini, regardless of who was wearing it, angered Guevara's relatives who said it trivialised his memory.
