This is Not My Hat 
by Jon Klassen

Klassen, J. (2012). This is Not My Hat. Boston, MA: Candlewick Press.

Little fish is excited because he has a hat and it fits just right. Unfortunately the hat does not belong to him. It belongs to a much bigger fish who had it stolen right off his head! Unbeknownst to little fish who thinks he is getting away unnoticed, the hat's owner is on his trail. When the witness who said he wouldn't tell spills the beans, things don't turn out quite the way little fish had hoped.

With very basic and minimal text, much of the humor of the story is told through the illustrations, such as in the big fish’s eyes and the crab pointing the way to the culprit.  Though the ending is not specifically stated in the text, the reader is left to infer the outcome based on the pictures.  

The dominant shape in This is Not My Hat is the oval.  Used to not only represent the main characters of big and little fish, ovals are also used to illustrate the underwater setting’s plants throughout the story.  This is significant in that little fish believes he can hide and will be safe in the tall plants.  The shape of the larger fishes’ eye is very telling as well, as you really gain a sense of his thoughts and emotions through even the slightest change in its shape and direction.
