The child on the left is from an image supplied by the campaign, at a time when most of the childhood images were provided courtesy of Maya Ng. The child in the centre and on the right has been shown on the Mark Nedasandjo website and was identified as 'David'. Don't you just love it that the the three of them are identical? Now you've got triplets to worry about.
It's really quite simple when you think about it, all you need to do is tell us which one isn't like the others.
OK, in the batch here, the top row has 0 on the left, and the two to the right are of David (and part of Marks right arm).
The bottom row left one and one next to it are of 0.
To figure out who are the two on the center right and right most, I’d need to see the larger picture around each. (First guess on them is they both are of 0, but would need surrounding area )
