Public Sculpture - Print-a-Day-21

This is number 21 in the series "Print-a-Day for 30 Days."

This is a sculpture located in downtown Omaha.  I wonder if the artist considers the graffiti as a defacement or if it was expected as part of a public living art project?

I selected this photo for the printing project because of the two strong colors and the gradient in the sky.  By the way, even though the photo was taken in bright sunlight, fill flash was needed to light the graffiti.
