These photos of telegraph messenger boys taken at the turn of the 19th century seem innocent and almost charming on the surface. However, most of the children led troubled lives that involved drugs and alcohol. Lewis Wick Hine, an American sociologist and photographer joined the National Child Labour Committee in 1908. He spent ten years interviewing and photographing messenger boys and as a result exposed how they were cruelly exploited. The captions for each of these photos are attributed to Hine.
