I kind of remember somebody "posting"* a streetview photo of either The Post or the building that's there now. Don't remember any particular logo for the cardroom, though. Mike Spinetti at one point acquired a supply of Post chips in near-new condition, perhaps he knows something more about the place. From what I know, yes, the cardroom was not around for too long. That might square with the chips being in such good condition.

152 Post Street is now an Indian Restaurant. No rats to be found there!
