The Essential Calvin and Hobbes

The Treasury books are reprints of the black and white collections. What makes them special is that they are large-sized, with full color Sundays, and each one starts with a special full-color story in large format that has never been previously published. If you haven't started collecting yet, buy the treasuries instead of the first 6 books in the collection. The stories are the same, but you get the added intro stories, and full-color Sundays.

The Essential Calvin and Hobbes : A Calvin and Hobbes Treasury

The intro story is A Nauseous Nocturne. An Excerpt from this story was reprinted in The Tenth Anniversary Book, but here it is complete and in larger print. The Essential Calvin and Hobbes includes all the stories from Calvin and Hobbes and Something Under The Bed Is Drooling.
