I love those photos.
For what it's worth, the pic of the kid with the blank slate is likely going to be used for propaganda. It's a common trick to have people hold up blank white boards, so you can superimpose whatever message you want. Whether or not that was their intent, I'll never know, but my guess is that SOMEONE will end up trying to exploit that picture.
Yea it's cynical but I'm trained to be suspicious and no way in hell will I ever let myself be photographed holding any blank, light-colored board, paper, or sign...
