Graffiti artist Stik's life painting on the streets
He has lived in a homeless hostel and dodged police to put his mark on the city, but now London-based graffiti artist Stik is invited all over the world to paint huge murals of stick figures, many of them offering social comment.
They can be seen in New York, Tokyo and London - where he has painted the tallest piece of street art in the UK, standing at 125 feet (38m).
Stik's works, which hang in the homes of Elton John, Bono and Brian May as well as being on the street, have been brought together in a book.
His latest piece, Sleeping Baby, has a limited edition print with 100 per cent of sales going to art projects at Homerton Hospital.
Stik, who refuses to talk about much of his life on the street, showed BBC News around his studio and some of his favourite works.
