Jon Klassen

Jon Klassen (born 1981) is one of the most important picture book creator-illustrators of the twenty-first century — a Canadian artist whose deadpan, minimalist, darkly funny books have redefined what picture books can do. His Hat trilogy — I Want My Hat Back (2011), This Is Not My Hat (2012), and We Found a Hat (2016) — are modern classics, and his distinctive visual style (flat colors, expressive eyes, vast empty spaces) has been as influential on contemporary illustration as Chris Van Allsburg’s or Maurice Sendak’s was on earlier generations.

Life and Career

Klassen was born in Winnipeg, Manitoba, and grew up in Niagara Falls, Ontario. He studied at Sheridan College and worked as an illustrator and animator, including work on Laika’s Coraline (2009) and the Cartoon Network series Adventure Time. His animation background is visible in his illustration work — his compositions have a cinematic quality, with careful attention to staging, timing, and the gap between what is shown and what is implied.

I Want My Hat Back (2011, Candlewick Press) was his debut as both author and illustrator and was an immediate sensation. A bear has lost his hat and asks various animals if they have seen it. The bear eventually realizes who took it (the rabbit), and the story’s ending — in which the rabbit has clearly been eaten, though this is never stated — created the template for Klassen’s signature mode: children’s books with dark subtexts that children find hilarious and adults find disturbing.

This Is Not My Hat (2012) won the Caldecott Medal and the Kate Greenaway Medal — a rare transatlantic double. A small fish has stolen a hat from a big fish and swims away, narrating his confidence that he will get away with it. He does not. The book’s underwater darkness, the fish’s eyes, and the gap between the narrator’s confidence and the reader’s knowledge create a perfect comedic mechanism.

We Found a Hat (2016) completed the trilogy with an unexpectedly tender entry — two turtles find one hat, and the story explores the tension between desire and friendship. The book’s emotional register — genuine affection and moral seriousness — expanded Klassen’s range.

Collaborations and Later Work

Klassen’s collaborations with Mac Barnett — Extra Yarn (2012), Sam and Dave Dig a Hole (2014), The Wolf, the Duck, and the Mouse (2017), the Shapes trilogy (2017–2019) — have produced some of the most acclaimed picture books of the decade. He also illustrated Carson Ellis’s The Skull (2023) and other projects. The Rock from the Sky (2021) was his first solo picture book since the Hat trilogy — a multilayered comedy about rocks, turtles, and meteorites.

Collecting Klassen

I Want My Hat Back first edition (Candlewick, 2011) signed brings $75–$200. This Is Not My Hat (Candlewick, 2012) signed as the Caldecott winner is $75–$200. We Found a Hat (Candlewick, 2016) signed is $40–$100. The Hat trilogy as a complete signed first-edition set is the premium collecting target. Klassen signs at events and has a strong convention presence. His collaborations with Barnett — particularly the Caldecott Honor books — are also sought. Original artwork, when it surfaces, commands strong prices. His influence on contemporary picture book aesthetics means demand for first editions should continue to grow.
