Despite the name, the cover of the book doesn't actually feature Calvin and Hobbes, but rather five schoolchildren around a teacher's desk. The book was written by Linda Holmen and Mary Santella-Johnson.
The book itself is divided into five sections, each based around a Calvin and Hobbes storyline. The strips are presented, and then followed up by a number of questions such as "In strip 7(d), what is Hobbes insinuating?" and "What do you think the principal meant when he said they had 'quite a file' on Calvin?" to help students analyze the stories.
The book is very hard to find, and copies in new condition price at $10,000.
