On a trip to Chicago, I saw this cool looking pipe apparatus underneath the L train on Wells. I liked how it didn’t seemed planned for and looked like it had been modified several times to make it connect properly. Thus, brings another edition to my series of pencil drawings with bright, pop-art-style backgrounds. I’d like to think of a snappier way to describe this series. If you think of a cool name, please comment below! Find more examples here.
