The first image I checked was the "Lincoln" image (It's not Lincoln).

There are three men in this picture, in a semicircle. A bearded man's head is visible near the upper right of the image. Another man, wearing glasses, is about a third of the image to the left - his arm is extended towards a round object below the bearded man. A third man is shown in profile in the bottom left - he also has his arm (wristwatch visible) reaching under the bearded man's head.
The second image had an even more vague description of a man looking down.

There are four men in this picture, standing around a large piece of paper laid out flat. Their heads form a diagonal line starting just to the right of the upper left corner. Two of them have their hands resting on the paper. The rightmost man is most detailed, wearing a jacket, his arm extended towards the paper. There appears to be scaffolding in the background.
This image is almost certainly a photograph.

Hopefully this isn't old news that just hadn't made it to the article and I haven't wasted my time :P
