Kai Vaalio (b. 1986) is an illustrator, comic artist, and a bit of a cosmopolitan as well. He’s written and illustrated underground comic books for adults about his travels in South-East Asia and Latin America — the latter even won Mondo magazine’s Travel book of the year award back in 2014. Recently he’s ventured into the world of illustrating children’s books mainly with Arttu Unkari’s Dad Man Series. Together they’ve made four books about this goofy detective and his clever little posse. The Dadman Series has received Storytel Awards and Runeberg Junior 2023 award nominations. Vaalio’s been on and off in the graphic industry since 2005 when he graduated as a graphic designer from Lahti College of Arts and Crafts. In 2018 he got his bachelor’s degree from Lahti University of Applied Sciences.
