THE GHOST IMAGE: MY VERDICT
This will be the sixth year of clues for me, so I'm starting to get used to what they will, and will not do. And though I cant discredit the possibility,
however small, that the fact that there is this background ghost image may be important, I can conclude that its
contents are most certainly of NO importance.
Heres the image flipped corrected to show the background.
As you can see by the color of the letters, their distortion, the fact that they are mirror image, and the shading indicative of a copy getting darker as it reaches the spine of the book, all point toward this simply being an artifact of this picture being a photocopy. Someone even pointed out earlier that the version of this pitcure on the web that doesnt have the ghost is an older image, suggesting that it has probably been edited to remove the ghost image.
Also, you can see in this image that there are actually TWO ghost images on top of each other. One from each page. Further indicating that this "ghost" was unplanned. Or, if it was planned, its contents are unimportant, as there are two opposite pictures and lines of text on top of each other.
There is no possible way that useful information could be expected to be extracted from this ghost. Therefore, only the fact that there is a ghost is important, or, it is an unplanned artifact.
