Eyes on the ground

I NOTICED SOMETHING QUIRKY about the sidewalks in Milwaukee. Many of the concrete blocks were stamped with an identifying marker that included a year and, sometimes, the name of the company that poured the concrete. Once I noticed them, I couldn't stop looking at them and – alas – photographing them. Despite the eye rolls and snickers from my companions, I continued snapping shots because I thought they'd make a cool collage.  Click to enlarge.
