About this person

This Is Not My Hat is a companion to Klassen's preceding picture book, I Want My Hat Back (2011), which was his first as both writer and illustrator. Both books were on the New York Times Best Seller list for more than 40 weeks; by April 2014 one or the other had been translated into 22 languages and they had jointly surpassed one million worldwide sales. Both books were recommended for children ages 5+ by the Greenaway judges. Klassen's Hat Trilogy was completed with the publication of We Found a Hat (2016).
