North Dakota. ”The men in this photo want to be just where they are. North Dakota holds the largest accumulation of oil found in America in forty years, and workmen have poured into the state looking for jobs while the drilling boom is on. The New Yorker sent German fine-art photographer Thomas Struth to the prairie land to document the scene. He did so with his meticulous eye for detail and photographic objectivity.” Photo by Thomas Struth, The New Yorker

Hollywood. ”Evan Rachel Wood is Hollywood’s girl of the moment, seen most recently lighting up HBO’s monumental melodrama Mildred Pierce, in which she played ultra-vixen Vida, and in Robert Redford’s new film about the Lincoln assassination, The Conspirator.

Washington, D.C. ”It’s not much of a photograph, I admit, but it may prove to be one of the most important political images of year. On Wednesday, the White House released this image of President Obama’s birth certificate, putting an end, perhaps, to the question of whether the President was born in the United States, as the Constitution requires. At the very least it may scuttle the presidential dreams of Donald Trump, who has turned the “birther” issue into a political platform and a form of self-aggrandizement. If so, this is a great, great photograph.” Photographer: Unknown, The Huffington Post, et al.
