Murals, they are pretty cool. Here is another one from down there in Lexington KY. If walk downtown Lexington you will probably spot this one, as it is huge, hard one to miss.
My wife went to the University of Kentucky in Lexington for one year, so when we drove through Kentucky we had to stop there for her see her old place and have a lunch. After parking the car I saw this interesting art on the wall and could not resist but take a photo.
