An early aerial-perspective chromolithograph sweeps across the Columbia University Morningside Heights campus — Low Library's great dome presiding serenely over brick dormitories and open athletic fields, the Hudson River shimmering in the distance beyond — in a view that shows the campus still surrounded by the semi-developed urbanism of the early 1910s, before Manhattan's relentless infill closed in. Postmarked Brooklyn, May 17, 1913, the card was dashed off by someone signing only initials — "E.B.S." — to a recipient in Sodus Center, New York, with a breezy update: "Arrived all OK, Mr. Abbott wishes to be remembered to you. We are all going to spend the day in N.Y." A snapshot of a Saturday excursion shared across the miles.
