Wow, I never even noticed that was an image in the background, I thought it was just a rendered texture. Looking at it now it makes sense actually. They photographed the CO toy. The real journal didn't have texture like that, trust me. That texture matches up perfectly to the toy, as does the ridiculous way the strap is tied. That makes it a lot easier actually. I'll photograph my journal tomorrow and share the image.
PS - Shame on the prop department for that tie strap in the photo, and for putting it on the cover facing the wrong way. But then, the End of Time was pretty bad in all other respects, so it's hardly worth complaining about.
