This copy includes two original drawings by the author-artist: the first drawing is on the front endpaper, and the second drawing is on a separate Pixar Studio notecard laid into the book.
Aaron Hartline is an animator at Pixar Animation Studios and has worked on such films as Up, Toy Story 3, and Inside Out. Aaron loves to sit and draw as the stories of Box and Circle jump around in his head. He lives in Berkeley, California, with his family.
From the publisher:
Circle loves to jump, but Box just falls flat. Oww! Box loves to sit, but Circle just rolls away. Whoa! They want to play together, but how? They figure out that Box can sit on Circle as Circle jumps to her heart's content. However, Box still experiences an Oww! every once in a while.
