The opening lines of "Back on Times Square, Dreaming of Times Square" by Allen Ginsberg: "Let some sad trumpeter stand / on the empty streets at dawn / and blow a silver chorus to the / buildings of Times Square, / memorial of ten years, at 5 AM, with / the thin white moon just / visible / above the green & grooking McGraw / Hill offices …"One of my favorite entries is for the Staten Island Ferry Terminal at Whitehall. It's an excerpt from Edna St. Vincent Millay's poem "Recuerdo": "We were very tired, we were very merry-- / We had gone back and forth all night upon the ferry." The words are actually printed along the side of the new terminal building.
The McGraw Hill Building at 330 West 42nd Street. See it here on a map and from the side in all its green and grooking-ness.
I think more places should have poetry and prose written across them like art.
