Collector: Lincoln photo uncovered in Grant album

Collector: Lincoln photo uncovered in Grant album:

"If it is indeed Lincoln, it would be the only known photo of the 16th president in front of the executive mansion and a rare find, as only about 130 photos of him are known to exist. A copy of the image was provided to The Associated Press.

Grant's 38-year-old great-great-grandson, Ulysses S. Grant VI, had seen the picture before, but didn't examine it closely until late January. A tall figure in the distance caught his eye, although the man's facial features are obscured."
