At the top of this page, you can see Jackson Pollock's painting, Silver and Black. Can you find his signature? The "J" and "A" are pretty apparent at the top left, and P-O-L-L-O-C trails diagonally down the right. According to Henry Adams, the K appears in a magical place called "not on the painting, you just have to imagine it," and the rest of the letters in "Jackson" are concealed in the messy area in the middle. What do you think?
