Does anyone know who the artist Scott Mutter is?

Scott Mutter is an artist from Illinois. I used to work for the pre-press operation that created the film for printing his posters. He will take 2 completely separate photographs and mesh them together so that they look like one photo. I believe his most famous posters are the "Escalator" which combines a photo of the ocean with a photo of a man walking toward a huge escalator; and the "Library" which combines a photo of the "stacks" at the University of Illinois and a picture of a Chicago street. His artwork is very popular on campus at the University of Illinois.
