IFS also included commercial and journalistic still photographers. This image depicts a group of women conductors of the Brooklyn Rapid Transit Company standing in a line at the pay window; a man at the window is barely visable. In December 1917, Brooklyn Rapid Transit, among other rail lines, began to hire and train women to be conductors during World War I. The photograph was published in Washington D.C. newspaper the Sunday Star (formerly the Evening Star) on February 3, 1918.
