A picture book is the first book in a child's life and his first encounter with the written word, so it is of extreme importance that it is of good quality. The quality of a picture book is a relative term with a multitude of criteria to consider. The paper will primarily touch on the historical development of the picture book and its components; such as interactivity, specific readership, etc., as well as mentioning its functions. The relationship between image and text, ie the visual and verbal layer of the picture book, will be described from the theoretical starting points obtained from several studies conducted by domestic and foreign authors. The role of the picture book as a link and form of communication between adult and child is an important component of the work, with an emphasis on the aspect of picture book interactivity. Special attention in the second part of the paper is paid to the biography of the contemporary writer and illustrator Kestutis Kasparavičius. His works "The Missing Picture" and "The White Elephant: Stories from Distant Countries" were analyzed according to several criteria - such as the use of stylistic means of expression, the correlation of text and illustrations, as well as the assessment of the quality of the story itself. All with the aim of describing and defining the features of Kasparavičius' individual style, which is famous for its use of irony and the inclusion of absurd situations. Kestutis Kasparavičius "revives" everyday objects in his stories, and gives animals that have no place in the illustrations and stories of other authors, a major role in his picture books (like fish in "Underwater Story"). The illustrations that made Kestutis Kasparavičius a world renown author will also be analyzed. Furthermore, the dissection of the work gave a new look at the "formula" of his success in the world of children's literature, which can be related to the aspect of attractiveness of his picture books as a consequence of the story's orientation to double readership (children and adults). His subtle and unobtrusive morality, as well as valuable life lessons incorporated in Kasparavičiuses picture books, give them the originality to which only a rarity of people can remain indifferent to.
