The Legend Of Zelda Encyclopedia/ Hyrule Historia/ Art & Artifacts Collection. All three books are in excellent condition, they have been part of my book collection so have been on display but kept away from natural light and only infrequently under artificial lighting.
These books have never been read but have been removed from their packaging just because they looked better without it. The Legend of Zelda Encyclopedia has some indentations on the front (pictured). I only noticed them when I came to take photos so I'm not sure how or when this happened, I have moved house twice since I got it so it could have happened then.
