What happens when two acclaimed children’s book authors with close ties to comics team up?

Mo Willems (www.mowillems.com) won six Emmys for writing Sesame Street and created Sheep in the City for Cartoon Network, where he also served as head writer for Codename: Kids Next Door before moving to such bestselling picture books as Don’t Let the Pigeon Drive the Bus! and Knuffle Bunny, for which he’s received three Caldecott Honors.

Jon J Muth started on such groundbreaking comics as Moonshadow from Epic (later reprinted by Vertigo) and The Mystery Play with Grant Morrison before becoming an award-winning children’s book author and illustrator of such books as Zen Shorts and The Three Questions.

Now, the two have teamed up for City Dog, Country Frog, a funny and touching children’s book about an unlikely friendship and the passage of time. To celebrate this collaboration, we got the two creators on the phone for what turned into a raucous and thoughtful discussion of what led to their working together.
