These creepy photos of American cities without people make them almost unrecognizable

For almost 40 years, photographer William W. Fuller has traveled back and forth across America, documenting his journeys.

However, instead of creating the typical postcard image, Fuller decided he wanted to make photographs of major cities in a way that makes them almost completely unrecognizable.

Fuller turned his series into a recently published book, entitledThe City: A Formal View of American Urban Architecture.

Fuller first started taking pictures of the cities he traveled to in 1981. He became interested in photography after taking a course in college under well-known photographer, Henry Wessel.

Growing up just north of Chicago, Illinois, and in Pittsburgh, Pennsylvania, Fuller was always close to, and intrigued by big cities.

Originally, he hadn't planned on making a full series of work — but his curiosity and fascination with skyscrapers and urban architecture kept him shooting. "In the beginning, I would just photograph cities that were interesting to me," Fuller told Business Insider.
