Guy Bourdin does not produce nice images: these are images of evocative power that cross commercial and art borders. He is/was an extremely influential advertising photographer who was given briefs that enabled him to apply his artistic vision to the creation of images to fulfil commercial objectives. Now that's already an interesting ethical dilemma, and whatever side of the debate you are on you would find this book important.
Texts on semiotics in advertising (see for example Judith Williamson, Decoding Advertising) frequently cite his work, because his images are so richly layered and textured, seeming to say one thing while they evoke several others. Some of his most famous and pioneering work was for Charles Jourdain, the shoe designer, in which the shoes appear as characters in dramatic scenarios peopled by sensual women in strange story lands.
