The first of four volumes, covering the artist's work in all media. The photo-mechanically reproduced illustrations by Picabia, which are a significant part his production, will be included in the relevant chronological volume. Most works on paper will be published in a later annex volume, along with works discovered after publication of the original 4-vol. set. The texts are bilingual, but the catalogue raisonné is only in English. Volume 1 covers Picabia's early Impressionist works, first experiments with Cubism and experiments with printmaking. It includes introductory material, a description of the methodology, a selected chronology, a biography of the artist, a critical essay by Arnauld Pierre, as well as exhibition information, bibliography, and indices.
