Banksy may be famous in the UK for his street art, but Blek le Rat has been adorning Paris with his artwork since the early 1980s. A new book, Blek le Rat: Getting Through Walls and an exhibition at The Black Rat Gallery in London examine his work.
Sybille Prou, one of the authors, is married to the artist and has photographed his work over many years.
