Children build the foundations of the future civilization; therefore, in order to understand and promote the culture of our country, the study of the effect of imagery in the works of Iranian illustrators associated with the stories of Iranian writers is considered as the research goal. Another goal of this study was to identify the elements that illustrators have been inclined to use to make more visual imagery over the past decade. The methodology of this research is historical and descriptive-analytical, and the collection of materials has been done through library and internet studies. The results of the review of books and images and examples from the age group “B and C” books by the Children’s and Adolescent Intellectual Development Center indicate that the use of fictional imagery in the illustrations of the last decade has been growing and more illustrators have taken fantastic elements in creating the story space. The most commonly used fictional imagery is imaginary space, and the smallest is imaginative characters.
