Diptych....what's that you say?

I have to confess, I didn't pay attention during art history lectures.  Fortunately, I still read and realize the importance of continuing to expand my view and vision.  Seems like I always knew there were images that seemed linked in content, design, structure and color palette...so here are three diptych photographs from my visit to Great American Ball Park.  Art? Probably not, but they seem like they have a relationship to each other.
