The photo is from a remarkable series of photographs in the Boston Globe on the war in Afghanistan. The caption to the photo reads as follows"
“A young Afghan boy gives the thumbs down to a passing NATO French Foreign Legion convoy near Surobi some 50 kms east of Kabul, Afghanistan,Monday, Nov. 9, 2009″ (The Big Picture).Photographs by David Guttenfelder and Jerome Delay for the Associated Press.
There is a really interesting piece on the photos on the website No Caption Needed which has this to say about the photograph above:
"When the “hearts and minds” of the people are a crucial factor in the mission, then photographs of ordinary people caught in accidental moments of time can reveal important truths".
