I have been doing some browsing and working in Flickr, and I came across this photograph of a stairwell at Jesse Hall on the Concordia campus. Look at the shadow. Many people have passed by this scene over the years, but only one person photographed it.
The Flickr link is here.
The photographer calls himself "Full Metal Photographer, but his real name apparently is Kelly Hoffart. He writes: "I took this picture in 2002 when I was taking a photography course at Concordia University." He is a superb photographer, as you can see from his blog. He also is a lawyer in Lincoln, Nebraska.
