All that follows is but my opinion based on photographic, video and written evidence that has accumulated over the years.
Below the fold is a 1:31 video that could be described as the “making of the Famous Photo, that of Phan Thị Kim Phúc running down a road after a napalm attack on her village. Please be advised that both the photograph and video are of a naked child. This is uncomfortable for all of us, but it is such a well-known photo that we feel at ease in running it here with a mere warning. If that troubles you, please read no further.
