Have You Seen These "Toynbee Tiles" Around Manhattan?

In my ten years here in New York, I have come across these tiles only a couple times. Once was around Times Square.  This time it was in the Bowery somewhere, and for some reason it felt much more eery a sighting.

But they are not just in New York City.  In fact, two dozen US cities have Toynbee Tiles. They are also in numerous South American capitals.

These tiles have some yet-to-be-established significance, much of which is speculated about in Jon Foy's intense documentary, Resurrect Dead (Netflix).  I saw the doc a couple years ago and was fascinated by it.

Although their origin and meaning is still unclear, there is a cinematic implication indeed to the Toynbee Tiles and their message:
