Here's a closeup of the apple with some iPhoto'd sharpening (no lines redrawn or retouching, just contrast, sharpening, and increasing the "highlights" and "shadows):
For comparison, here's the standard image of Karl Marx:
Now, the Anchoress — first link, above — has become "convinced that it’s simply a matter of the apples’ shading and the lighting." Absurd! It can't be just the lighting and the pattern of the apple peel. A magazine cover is carefully constructed and attention would have to be paid to any accidental imagery. The apple was chosen to be exactly the intended apple and subject to Photoshop tweaking and strategic placement of the lights to attain just the right level of perception and deniability. A good subliminal image must be seen and not seen. It must slide past the average person's conscious defenses and make anyone who insists it is there seem delusional. The Anchoress has retreated.
And so I say: To Newsweek! A toast!
IN THE COMMENTS: Irene says the image that might or might not be there was intentionally put there as "Tea Party bait":
I hear Chris Matthews now. "Marx? They see Marx? Wow, see how crazy they are?? They see socialists EVERYWHERE."
