The picture book is the first book that the child takes with curiosity and joy. Illustrations and text to the child provides all the information that interests him and helps him to adapt to his / her immediate environment. According to recent findings, the oldest preserved Croatian picture book is considered Mala zvernica, Hartman in 1864, while it was previously considered that it was the picture book of the Domestic Animals of Albrecht and Fiedler of 1885. The sixth volumes of the richly illustrated Basni with the drawings of young officer Alberto Nicholas Lauppert is considered to be the first illustrated Croatian book, and Lauppert is the first Croatian illustrator of a children's book, while first illustrator of picture books is Vladimir Kirin with color printed Childhood Health Booklet in 1927. At the beginning of the twentieth century, Leporello paintings appeared which are appropriate for children between 1.5 and 3 years. In addition to these picture books, there are pop-ups, multimedia photo books, picture books with children's drawings... It is important to emphasize the difference between the picture book and the illustrated book in which the image and the text are interrelated, but their connection is not of crucial importance because the text can stand alone and make a unified ensemle without illustration. With my research, I wanted to show that this difference does not present such a problem in working with children of early and pre-school age. As long as the illustrated book has illustrations and while the book is appropriate to its content and form, it can be used in educational institutions.
