This book, co-published with the Fundación Canal in Madrid, covers three series by Fernand Léger that attest to his original pictorial language, full of shapes and colors. On the one hand, it includes his works to illustrate the foundational essay of Cubism, signed by Albert Gleizes and Jean Metzinger. On the other, the lithographs with which he illustrated Rimbaud’s book Les Illuminations and, finally, more than fifty plates dedicated to the circus, a world of fun and freedom that fascinated him since he was a child. An essential volume to explore the search of a new order that was always among his obsessions.
