This is a first English translation of Delteil's 1924 catalogue, listing works by the artist and those done in collaboration with others. There is a list of cited works, names of collectors, printers, and collaborators. Many entries are in French and English, with at least one full page illustration for each lithograph. This new publication includes the addition of Charles Clément's 1879 catalogue raisonné (the 3rd & final edition), edited by Alan Hyman. It also presents an appendix by Clément of questionable works. There are additional contributions by Paul Joannides and James Cuno.
