Nintendo has released new concept artwork that was made and used during the development process of the first The Legend of Zelda game for the Nintendo Entertainment System released in 1986.
The newly released artwork comes in the form of several scans of hand-drawn grid design that features the layout of some of the game's most memorable environments, including dungeons and the overworld map.
Nintendo released the new artwork in honor of the franchise's 30 year anniversary. On the company's official blog it has also published animated gifs that compare the artwork with the final results.
