Agree. I think the actual message of the tiler(s) has never been totally sane, but they are fascinating.

I figured that the original guy was retired, still cool to see a tribute in the wild though.

Honestly I forgot to take a specific note when I saw it. But based on my Google maps timeline it looks like I was walking from the chinatown gate to North Station. It was right next to a crosswalk in an intersection so it would be hard to miss.
