Please note that individual graphics are often used to "watermark" some epubs in order to originally identify who the book was sold too. Information can also be encoded right into the pixel values themselves (steganography) that can not be detected visually, and further "watermarks" can be also be found in hex css fields such as colour values.

I have found 2 books that used multiple ways to hide their "watermarking". Never understood why on earth you would hide a watermark but .... could this be one of those rare cases?
