Edgar Valter (1929–2006) was a graphic artist, illustrator, caricaturist, and children’s writer. He illustrated more than 250 children’s books, including masterpieces of Estonian literature authored by Eno Raud, Ellen Niit, and Aino Pervik. He himself wrote 15 works, the most popular of which are The Poku Book and its sequels. Valter’s writing stands out for its sincerity, warmth, and unusual sense of humour. He crafted stories and characters that have since become household names throughout Estonia. Nestled in the southeast of the country is even a nature-inspired Poku theme park – Pokuland. The Estonian Children’s Literature Centre in Tallinn also has a gallery dedicated to Valter’s illustrations.
