"This is a group photo of me with my co-workers in the early 1990s at the Los Angeles Chamber of Commerce. After careful inspection of the photograph, I noticed a face immediately to my left, also facing the camera. I asked the employee who occupies that office space behind us if she knew who this person was. No she did not, she replied. She also confirmed that she was not in her office that day the photo was taken; therefore, no one could have been in her office at any time. To this day, this phenomena remains a mystery."
