Mexican wrestler El Hijo del Santo is pictured during a photocall for Lucha Libre in London, on December 4, 2008. El Hijo del Santo is reputed to be the greatest living Luchador and heir of the Silver Legend. Lucha Libre is authentic Mexican free wrestling and features strong men in mysterious and elaborate masks. Sixteen of the biggest names in Mexican Lucha Libre are to perform at the Roundhouse from 6 to 9 December. Lucha Libre is mainly based on acrobatics and complex, fast-paced manoeuvres as these masked men throw each other around the ring.
