A man is looking at a photograph of someone on the wall. His friend asks, 'Whose picture are you looking at?' The man replies: 'Brothers and sisters have I none, but that man's father is my father's son.' Who is in the photograph?
His own son
'My father's son' with no brothers or sisters must be the man himself. Therefore, the phrase simplifies to 'that man's father is me,' making the person in the photograph his son.
