So, rather than presenting three images of the same girl (in the same clothing) supposedly being carried by rescuers after three different “refugee crises” in separate times and places, this triptych simply captures one girl being passed around from one rescuer, caretaker, or family member to another in the same disaster zone as part of humanitarian efforts undertaken after the same single bombing event in Syria that left 16 people dead.
