The book features development art from all the 12 episodes in Book One: Air. The cover art is different from the original product image. It's as good as the first art book Avatar: The Last Airbender: The Art of the Animated Series. The Legend of Korra: Book 1 – Air, The Art of the Animated Series is a nice addition to that experience.
I can still remember the strong nostalgia I had while watching the first episode of The Legend of Korra: Book 1 Air, recalling all the characters from the previous series, and watch how time has passed and given us a new generation to look upon.
