You might hear Peanuts from most people when discussing the best comic strips of all time, and it's hard to argue against that. Unless of course you fire back with Bill Watterson's eternally popular Calvin and Hobbes, the story of a young boy with a stuffed tiger for a best friend and an over-active imagination.

There's getting the formula rolling, and then there is perfection. Calvin and Hobbes is the pinnacle of comic strips, and every single one published from 1985-1995 has been released on iBooks.

Three volumes, titled The Essential Calvin & Hobbes, The Indispensable Calvin & Hobbes, and The Authoritative Calvin & Hobbes are now for sale for $12.99 each, and any one of them can make any blue day happy. Any boring day exciting. Any cloudy day sunny.

If you grew up after the run of Calvin and Hobbes, do yourself a favor and throw money at this. It's a comic all about youth, adventure, friendship, and some serious reflections on life itself. They don't make them like this anymore, challenging young readers to think about what they are reading and entertaining them at the same time.

This is one holiday purchase you won't regret. Bill Watterson's masterpiece can give you and your kids countless hours of enjoyable reading.
