The Lord of the Rings. When I saw this picture it was so suprising! I was like "Why is Gandalf so short! Why are the hobbits so tall!" I knew it was behind the scenes, but you feel like Gandalf is really short here.
My all time favorite set of books ever. I love many different books but these will always be my favorite. (I haven't read The Silmarillion yet though. Reading it as soon as I can get my hands on a copy.
