Present & Correct just posted this on their facebook page. WOW. Needing to pick up my jaw from the floor. These two installation pieces are so beautiful. The first is by Marianne Viero, who mounted these books onto a wall.
The second from Michael Sirianni who layed out a wonderful color gradation of books.
Both utilized the sun to bleach the covers of the books to create these amazing yet subtle effects. (images via here and here.)
