Because plates are printed in a separate process from letterpress text, and because the images in Soldini's work are not closely related to the text, different copies of the book have the plates inserted and bound in different locations. In this copy from the Smithsonian, this is the illustration facing the first chapter, but compare this to the Getty's copy of the book.
