And unusual is an understatement. Founded in the early 2000s by a reclusive Dutch illustrator and a Finnish typographer, Tonkato has no website, no social media presence, and no distribution through major retailers. Instead, its “Unusual Children’s Books” series (each volume numbered, with 51 being the latest) appears sporadically in small print runs of 200–500 copies, sold through select indie bookshops and underground art book fairs.
One collector, who goes only by “The Curator,” told us: “Tonkato 51 isn’t a book. It’s a permission slip for a child to ask, ‘Why must stories end happily? Why must endings exist at all?’ That’s rarer than any first edition.” Tonkato’s “Unusual Children’s Books 51” is not for everyone. It will confuse some parents, unsettle a few librarians, and likely never appear on a Scholastic Book Fair poster. But for the child who already knows that the moon doesn’t follow them home, that monsters sometimes apologize, and that silence can be a sound worth listening for—Tonkato 51 is a small, strange treasure. tonkato unusual childrens books 51
Part fable, part field guide. Each spread features a sound (the crack of a glacier, the hum of a landline dial tone, the whisper of a dodo’s last call) and a small die-cut hole. When you press the hole against your ear, there is silence—because the sounds are gone. The book comes with a warning: “For children who already know what loss means.” A quiet bestseller in the series. And unusual is an understatement
She points to a small 2024 study where children were given standard picture books versus Tonkato-style narratives. “The unusual books sparked longer conversations, more interpretive drawings, and genuine emotional vocabulary—like ‘confused in a good way’ and ‘happy-sad.’” Because each Tonkato volume is hand-assembled and often incorporates unconventional materials (recycled circuit boards, fabric scraps, edible ink on one notorious edition), copies of earlier catalogs now fetch hundreds—sometimes thousands—of dollars.
