Quite simply, this volume represents the definitive source of information about Renoir's lithographs and etchings, supplaunting the nearly-impossible-to-find Stella Catalogue Raisonne. Even a casual perusal of such venues as "ebay" is sufficient evidence that serious collectors must rely upon both skepticism and education. This volume is a steadfast companion in seeking genuine Renoir masterworks, an absolute necessity for the graphics collector or gallery.
