The booklet that Bruce Lee, pictured here in Enter the Dragon in 1973, used to teach himself Kung Fu has sold for £52,000

The booklet that Bruce Lee used to teach himself Kung Fu has sold for £52,000.

The Enter the Dragon star made his own modifications to the illustrated manual for the Wing Chun version of Kung Fu to create his own unique style.

Notes alongside the pictures included 'grasp the opponent hard when he blocks your right punch, and kick him while jabbing him' and 'from straight hand punch, bend and strike violently at opponent's temple.'

On another page he wrote: 'Right hand block; left go over right and right pulls back immediately and punch out or back fist after swing'.

Lee called the adapted style Jun Fan Gung Fu, which translates as 'Bruce Lee's Kung Fu' which he taught to others to make ends meet after moving from Hong Kong to Seattle, US, in 1959 aged 18.

Lee gave the pamphlet, which has his name and address stamped on the inside cover, to his friend and assistant instructor Taky Kimura, who continued to teach his art form after the star's death.

Lee's annotated booklet, which has never been published before, sold for £44,000 at London's Bloomsbury Auctions. With all the fees added on the total price paid was £52,000.

Tragic Lee had used the pamphlet as a teaching manual while trying to make ends meet after moving to the USA from Hong Kong in 1959 when he was 18

Lee used the illustrated instruction manual for the Wing Chun style of kung fu but made numerous handwritten notes about the moves

Lydia Wilkinson, from the auction house, said: 'The pamphlet is in Mandarin with diagrams and instructions on Kung Fu, and Bruce Lee used this when he was teaching Kung Fu to make ends meet after moving to Seattle.

'It was from a time before he was famous and is definitely his because it has his name and address in Seattle stamped onto it.

'The interesting thing is that Lee has annotated the pages with his own notes in English detailing his tweaks and variations on the moves.

Lee became a superstar on the back of films like Fist of Fury, Way of the Dragon and Enter the Dragon

'He had his own name for his new style, naming it after himself. It's almost as if he knew he was destined to be famous and wanted to leave his mark on the artform.

'Bruce Lee is widely regarded as the most influential martial artist of the twentieth century and is a worldwide cultural icon, almost synonymous with Kung Fu itself.

'Signed material by him is exceptionally rare and this book gives an unprecedented insight into his creative process and philosophy.

'The star we see in the films he made was the ready-made package but this shows the behind-the-scenes development of Bruce Lee.'

Lee, born Lee Jun-fan, went on to found the Jun Fan martial arts studio in Oakland, California, and was later 'discovered' by Hollywood at the Long Beach International Karate Championships.
