This dissertation reports a proposal of identification and description of the existing configurations in the resources and techniques used in paper engineering, as narrative and illustrative devices in the construction of the mobile book. The objective was to demonstrate the relations of coherence and cohesion between verbal and non-verbal texts applied to the pop-up book. The pop-up book (mobile book) permeates and captivates the universe of children and youth with their peculiarities and multiforms. The mechanisms of paper engineering become increasingly bold in order to attract and expand the sensory and synesthetic potentials that stimulate the imagination and intensify the reader s interaction with reading. As methodology, studies were developed on the functions of language, on coherence and cohesion that are established in the design of a pop-up book. Twenty thousand leagues underwater, from Sam Ita, published in 2010 by Publifolha served as an exemplary case. With the understanding of the relations between the literary, illustrative and sculptural texts, it was possible to conclude that, taking advantage of the magnitudes of the paper sculptures, the illustrated bases of the pages and the dynamic elements of the comics to guide the narrative, enabled the different languages become complementary. Thus, studies on verbal language and non-verbal language are equally important, since most writers, designers, and paper engineers have the same intention, to collaborate and add value to the book, be it pop-up, picture book, book toy or any other branch of the picture book. In Sam Ita s adaptation of the sovereignty of pop-ups and the creative dynamics of comics, they sharpen the imagination and especially the sensory and synesthetic senses of the reader.
