When were those photos taken?
The one on the left, the Ted Baxter looking one is younger, wears the suit. Has seen sunlight recently.
The one on the right looks as if he has had plastic surgery which raised his right eye too much. He looks like a basement dweller. Anemic. The suit wears him.
As to the signature, why would one add/remove the Jr.? That's something one does their entire life.
