"The blue is in agony, because everything is a question of pain. From end to end. From edge to edge. From his own pain, that of this anonymous child who turns his back on us." The Fléchette series sets the autochromes of the Archives de la Planète, made at Albert Kahn's instigation between 1909 and 1931, in dialogue with texts by contemporary writers: each volume is composed by an author invited to take hold of a single plate and write from it. Every volume opens with a reproduction of the chosen autochrome, which can be read both in opacity and, against a light source, in transparency, so that the plate can circulate again.
