I read this book when I stayed overnight with friend house in Boston. (Thanks again for the Bloody Marys Jake and Lisa!) Basically it's just photos of signs and things that have been improved with a FUCK sticker. You can get the idea from Fuck This Website.
Since I now know that Oser printed out the initial batch of FUCK stickers, I'm less excited about the project. I thought he was documenting a more independent movement.
Unfortunately I didn't take care to note my favorite FUCKed photos in the book, so you'll have to pick it up yourself to find out. Just don't expect to do so at a library near you, because according to WorldCat, only about 25 of them own it.
