I went to Copenhagen for a few days and put my eyes in vacation mood. My eyes went up and down, and all around. That is usually how I do to see the surroundings. Mostly I looked down. Mostly, but not always. On the ground were large plates of thick iron for us pedestrians to walk on over ground work here and there. They all had, I guess, the owners initials. Very graphic. I like to do series. When my eyes find one, of whatever, they always find more of the same.
