Funky, if you have the Revelation book, I would recommend that you look at that illustration close up. It loses much in the scanning process. My outlines are "approximate" and are not perfect. Remember the context of the hidden image is that it is hidden in the clouds, and therefore, the face should be made to blend in with the clouds, thus is the point of a hidden image within an illustration. If it were perfectly discernible, we would not even be having this conversation, and if it were perfectly discernible . . . you would not have seen . . . a frog, wasn't it? I won't spend anymore time trying to convince you, but I do encourage you to see the actual illustration as it appears in the Revelation book.
While I am a true believer when it comes to the use of hidden images in some of the illustrations of the WTBTS, I do not for a second assert that every single illustration contains hidden images. Those that are questionable I do not even comment on. I did not seek to embellish what appears in the illustration, but only outline the major features to give you and idea what to look for.
First of all, by "subliminal art" we mean art that contains optical illusions that are dramatically obvious once you see them, but completely invisible until you do. The most effective subliminals are not in the details but in the big picture. A fleeting, holistic glimpse that arrests the eye and in a nanosecond converts to what it is. There are many ways to make subliminal designs. For example, you can use figure figure-ground illusions, or double exposures in which the hidden image is "embedded" in the visible image. Faint images can also be perceived unconsciously . It is not an excact science and each hidden image must be made to blend into its contextual elements, therefore you will never see one perfectly drawn. If you don't get it, then you won't get it, my friend.
Kind Regards,
