Many of you that love reading books maybe do not imagin what some people can do with them. I would define it "violation of book's dignity". Somebody will cal it Art. Well, the first pic maybe.
I wrote about these harassment different times, here I make only summary of that old posts and add one new way of artist's expressions in this "niche".
This is The Fore-edge Painting and you can find many other examples
in this site
Other 2 types of art you will find
here 

And finally the new one I found today
here -with many other creations.

Do you love books?
What do you do with them?
