I don't remember how or when I stumbled upon Brian Dettmer's work, but that is besides the point. His work consists of books that he cuts away at. I love the the process to get to the finished piece-- he seals the edges of the book and then cuts away page by page revealing images or words/phrases that are of interest. Dettmer says on his website "...Nothing inside the books is relocated or implanted, only removed. Images and ideas are revealed to expose alternate histories and memories." Check out his amazing work here.
