The Flatiron Building, originally called the Fuller Building, is so symbolic of New York City that it seems like it has always been here, but this vintage photo from 1902 showing the Fuller Building under construction proves otherwise.
The original photographer’s name has been lost to history, but it was published by the Detroit Publishing Co., one of the largest suppliers of vintage photographs to the Library of Congress, giving over 25,000 glass negatives to the collection, including this one.
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.
