This is such a great photograph, and really captures the time and moment. It's Don Letts walking towards the police lines at the Notting Hill carnival in 1976 (when it all kicked off). It was used on the cover of 'Black Market Clash' by The Clash, and he later worked with Mick Jones of The Clash in Big Audio Dynamite, as well as doing many other things (DJ, manager, film maker etc). What a cool bastard.
This guy even has it as a wall painting, done by his wife. I must say - I'm impressed. A top(per) job.
