Sorry, I couldn't resist.
I would also like to call your attention to the painting to the left of DeNiro. It's President John Tyler, painted by George Peter Alexander Healy in 1859. According to research I've been doing on White House art, it was one of President Clinton's favorite paintings because, according to Hillary Clinton, "it shows him tearing up the newspapers."
