The address side of a picture post card mailed from Sunbury, Northumberland County, Pennsylvania, to Brooklyn, New York, postmarked at the Sunbury Post Office on 17 January 1907, at 8 a.m. Sunbury was a major mail distribution center. At the time, the card would have traveled directly east in order to get to New York and thus would have avoided the Lykens Valley completely. Mail sent south to the Lykens Valley would have traveled down the railroad toward Millersburg and then routed to its destination from there.
