Brothers and Sisters I have none, but this man's father is my father's son.
Whose picture is the man looking at?
In reality, this would only be true if he said he was looking at his father's son (given that he has no brothers or sisters).
However, since he is looking at someone whose father is his father's son (himself), we can tell he is looking at a picture of his son.
