Can you see, just behind the man's head and to the left, the faint image of another face? Click the photo to enlarge it for a better view.
This picture hangs in the West Virginia Building at Jackson's Mill-WVU Conference Center. I can't remember who the man in the portrait is, but apparently he's sharing the canvas with someone else. Is it the man whose photo is on the desk?
If anyone knows the history of this painting, please share!
