With all due respect, I don't think I agree with you.
In the 1970's, those wide wrist bands were the in thing. But look carefully at these two--the one on the boy in the airport has edges that extend well beyond the watch face; the one on Obama does not. Different.
He's thinner--look at the arms and ankles. His mouth is narrower--clearly much narrower. His nose is narrower.
Obama is just not the boy in the airport picture.
The picture I do have difficulty with is the family picture on the couch in Indonesia. If the boy there is presented as Obama, he doesn't look like either the yard picture here or the family Christmas picture from 1971.
Also a problem is the lack of an explanation for the half-brother being in Honolulu in 1960. They really got married in Honolulu and the half-brother son came for the wedding? If so, we ought to find the wedding somewhere and it will make it more difficult to put Stanley Ann in Kenya in that time frame although I remain of the view that likely that is where she went.
Incidentally, the little girl is the Indonesian half-sister who is now one of the primary sources of information and pictures.
How old is Malik? Would he be around 10 in 1960-61?
I thought that BO, Sr was in his early 20s when he met Stanly Ann. He would have only been a early-mid teen when Malik was born if Malik was 10 in 1960.
We disagree re the boy in the two photos then. In the back of the airport photo to the left of the Dad’s head is what looks to me to be a 27” or bigger color terminal. That can help date the photo too.
