Glazer, Nathan. "New York: the 'old city'." The Public Interest 125 (1996): 61-79.
Excerpt: It was not much noted, or indeed noted at all, that the Million Man March in Washington last November took place in front of what was described in the 1937 Works Progress Administration (WPA) guide to Washington as the “the largest and most costly piece of statuary in Washington.” This is the Grant Memorial, the major monument in Washington to the Civil War. It is 252 feet long.
