This hasn't been mentioned so I feel obligated to make it known - I was viewing page 1 of the MMT on my iPhone which allows me to change the size / perceived distance of the image easily and this is what I've found -

If you were to view the page itself as a face looking at you, it becomes quite apparent that the MMT/BEATLES image forms an open eye/eyebrow, while the seemingly randomly circular bus image forms a closed eye, a WINK, which holds a heavy significance in Masonry, as well as other mystical systems - here is an excerpt from a paper on Symbolic Anthropology

"Consider, he says, two boys rapidly contracting the eyelids of their right eyes. In one, this is an involuntary twitch; in the other, a conspiratorial signal to a friend. The two movements are, as movements, identical; from an l-am-a-camera, "phenomenalistic" observation of them alone, one could not tell which was twitch and which was wink, or indeed whether both or either was twitch or wink. Yet the difference, however unphotographable, between a twitch and a wink is vast; as anyone unfortunate enough to have had the first taken for the second knows. The winker is communicating, and indeed communicating in a quite precise and special way: (1) deliberately, (2) to someone in particular, (3) to impart a particular message, (4) according to a socially established code, and (5) without cognizance of the rest of the company. As Ryle points out, the winker has not done two things, contracted his eyelids and winked, while the twitcher has done only one, contracted his eyelids. Contracting your eyelids on purpose when there exists a public code in which so doing counts as a conspiratorial signal is winking. That's all there is to it: a speck of behavior, a fleck of culture, and--voilý!--a gesture."


Happy Hunting! Cheers.
