Sorry Quinlad but I get so used to you having a pop at me, I thought you were doing it again.
I don't really think that a German camera man would have dared to enter a wagon load of Jews, especially how the Germans crammed them in, just to take pictures of the outside looking from the inside, why would he? Unless it was specially setup and the boy was posing?
Hardly a subject for Nazi propaganda purposes, but on the other hand it would be for Jewish purposes.
