Found on http://www.amusingplanet.com/2011/05/dirk-skrebers-car-crash-sculptures.html where the painting behind the WW2 monument is discussed, it's an art deco piece titled Manhattan Skyline, painted by artist Louis Lozowick at the height of the art deco movement as a Works Project Administration commission. It's 18 feet tall, and in the Farley post office on 8th Ave.
