Physical graffiti. Not to be confused with metaphysical graffiti, through which tagging can happen in 3-D (among other dimensions)… I’ve never climbed this stairway but I bet it doesn’t lead to heaven.
Oh my word did I ever fall in love with this place again today. First time since the late 1980s that I was at the Garment District and Dollar per Pound in Cambridge. But you can bet your bottom buck that we will be seeing (a lot) more of each other in the future.
