Recently there was an article in the NY Times entitled "Behind the Mysterious Symbols Spray-Painted on Our Streets," with the subtitle "All over New York’s sidewalks and sewers, colored markings hide in plain sight, telling construction crews where to dig and creating accidental art."
I was so excited to read it because I have been curious about the symbols and colors for a very long time, and even made a few small paintings about the markings I saw on my walks when I was working for a nearby city, and as I walk in my neighborhood.
Below is a screenshot from the NYT times, and below that three of the paintings I created in 2021.
There are new markings in my neighborhood now, and I am considering a new larger painting that incorporates my old and new photos of them.
