This photo was taken by Lewis Hine, an American sociologist and photographer. In 1906, he photographed life in the steel districts of Pittsburgh and in 1908 he became the photographer for the National Child Labor Committee. Over the next ten years, he documented child labor across the United States and his photographs were instrumental in changing child labor laws. This image was taken in 1911 inside the Yazoo Mills Co. Yazoo Mills was founded in 1902 in Yazoo City, Miss. In 1928, the company moved to Brooklyn, N.Y. and then to Hanover, Pennsylvania. Yazoo Mills is still in operation and manufactures paper tubes, among other products. Proudly recognizing the company's roots in Yazoo City, the company continues to be known as Yazoo Mills.
