From the perspective of his 90 years of age, from the height of being a legend in photography, William Klein looks back and selects his favourite works, those that he considers to be the best in his whole career, in order to pay homage to photography itself. This book, not by chance titled Celebration, is a tour to his most emblematic works: unique instants captured in New York, Rome, Moscow and Paris, in powerful black and white or striking colour. A true celebration of photography. This volume also includes a text by the author in which he reflects upon photographic art and explains what prompted him to make this sort of director's cut, this exceptionally personal selection, which brings together the works that, in his view, have made a contribution to the world of photography. A small-format but high-voltage volume that, page after page, makes it clear why Klein is one of the summits of contemporary photography.
