Eugene de Salignac was the official photographer of the NYC Department of Bridges from 1906 to 1934.
During that time, Salignac captured over 20,000 photos as large, glass-plate negatives which have been preserved in the municipal archives for us all to enjoy.
One of said 20,000 slides was this iconic New York City photograph titled “Brooklyn Bridge showing painters on suspenders, October 7, 1914.”
This photo is in the public domain in the United States. This applies to U.S. works where the copyright has expired, often because its first publication occurred prior to January 1, 1923. See this page for further explanation.
