The other thing about trying to equate these two images below, besides the fact that one features a baby and the other a little boy, and the clothes and hair of the mother in each are completely different, as is the coat of the boy in the denim jacket compared to the baby, is the fact that they are capturing the same moment in time, yet, the couples are not doing the same thing.
In Altgens, the boy is facing the street and looking down. He's definitely awake. In Towner, the baby is cast over the shoulder of the mother and is either looking the other way or is fast asleep. They can't possibly be the same.
To say that those two pairs are the same persons, you would have to either be the most stupid mudderpluck to ever walk the face of the Earth, OR you're working for the other side.
