I don't know John Jr.'s autograph well, but what a great pic to have his autograph on if it's real. That is one of the most iconic pictures of American 20th century history. Not only was John-John saluting his fallen father, it was actually little John's 4th birthday on the day of his father's funeral! Probably most Americans were not aware of it at the time, or they would have been crying even harder.
Right?
Have not been able to find another for reference.
Seems like he would not sign this photo for personal reasons.
Its either a bad taste forgery or a very special item.
You are correct. I always thought he looked a little small for a 4 yo, but that's because he was 3! What a moment. I'm pretty sure if I had been watching that, I would have lost it.
