I had to “enhance” the illustration to see what was going on here, but this sure looks like a riveting game of sidewalk chess, which used to be a scene close to 5th Street and which then got kicked over to the other side of 6th Street and which then got regulated out of existence.
But along with the chess came sidewalk craps, shielded from view by the chess people. Other things came along with the chess as well and that’s what led to its demise. One wonders why our City Family kicked the chess ppl out from 5th and Market in the first place…
