She was met by Astrid Lindgren, who had just finished writing the book Mio, my Son and who could see immediately that Wikland was able to “draw fairytales”.
Wikland did a test-drawing for the book and after that her collaboration with Astrid Lindgren continued.
Wikland has said that Astrid’s writing continually makes her see inner pictures.
She also derives inspiration for her pictures from real life.
In the same way that Astrid Lindgren wrote for “the child within her”, Wikland often also draws for the child within her.
Ilon Wikland is the artist who has illustrated the greatest number of Astrid Lindgren’s books:
The Six Bullerby Children (a.k.a.
