Sq. 4to. This is two books in one. It is a fully illustrated reprint of the catalogue raisonn by Hdiard from 1906, which was not originally illustrated. The editor Rainer Mason, then director of the Cabinet des Estampes of the Muse d'Art et d'Histoire of Geneva, incorporated the catalogue into an exhibition catalogue to which he added additional illustrations and essays by Yves Bourel, Claude Ritschard and Chantal Oederlin.
