Photoshop image manipulation

I've would like you to 'clean' the pages an old book (photo), thus removing all text and elements. You need to make sure the authentic look does not get changed. I removed a little myself, but got tired of manually removing all pixels (pixel-by-pixel), I am sure there is a better method of doing it. This is a low-res example of the photo: [login to view URL] As you can see, I removed the top half of the right page, your work needs to look the same (or a bit better). You also need to retain the existing discolorations and smudges on the pages and work from there. This is absolutely vital, or else it will look 'flat' and 'photoshopped'. For a photoshop-expert, this is a piece of cake, hence the low budget.
