I received the following photo from a gentleman named Bob Martin. A few years ago, Martin was reading David McCullough's book Truman, and a photo of construction in the White House caught his eye. It was taken during remodeling around 1950 by National Parks Service photographer Abbie Rowe. The apparent apparition is clear and startling. Compared to the other men in the photo, its size scale is accurate. And if this were due to some motion or long exposure effect, the rest of the photo should be affected, as well.
