When it comes to all ages comics, one body of work that tends to hide in plain site is Mo Willems's massively popular series of Pigeon picture and board books for younger children (and anyone who reads to or with children). Circulating in bookstores, libraries and generally anywhere where kids are found since the 2003 release of Don't Let the Pigeon Drive the Bus!, Willems' series of word-balloon infused titles exude all the charm and humor you'd expect from a Sesame Street, Codename: Kids Next Door and KaBlam! veteran and, ten years later, are probably owed for familiarizing an entire generation with the mechanics of sequential art. Today Disney Publishing Worldwide adds yet another dimension to the creator's work in comics and cartooning with the release of the aptly titled Don't Pigeonhole Me! Two Decades of the Mo Willems Sketchbook, which as the name makes plain, collects 20 of the creator's more personal works.

Unlike Willems's Pigeon and similarly kid-friendly Knuffle Bunny series of books, these sketchbooks aren't necessarily for small children, with Disney stating this release "reveals the author/illustrator at his most truthful, most experimental, most grown-up. Most Mo."

Having been released mostly only to industry professionals, family and friends since the early '90s, hardcore Willems fans have had to wait awhile to get their hands on this material. Featuring a foreward by The Very Hungry Caterpillar (and dozens of other books) author Eric Carle and 288 total hardcover-bound pages, this comprehensive version will probably prove worth the wait, though.

You can scope out a smattering of pages from Don't Pigeonhole Me! Two Decades of the Mo Willems Sketchbook below.
