This work is based on the importance of children’s exposure to literature, through the act of reading, telling and hearing stories, for the possibility of human formation. This article therefore reflects on the importance of children's literature for the appropriation of socially constructed knowledge by young readers. Considering that the genre of children’s story is full of characters that enchant children, the work The jolly postman by Janet Ahlberg & Allan Ahlberg was selected, to demonstrate the insertion of the real and/or unusual, as well as the intertextual relations with the wonderful tales present in the plot.
