Dappled summer light filters through ancient maples onto the fieldstone walls of Washington's Headquarters in Newburgh, New York — the Hasbrouck House where General George Washington maintained his longest wartime encampment (1782–1783) and where he issued his proclamation refusing a military kingship, one of the most consequential acts in American democratic history. Ladies in white Edwardian dress sit on the lawn benches, lending this hand-colored German-printed card an air of genteel Victorian patriotism entirely in keeping with the era's reverence for Revolutionary monuments. Postmarked Newburgh, N.Y., September 22, 1907 — six years after the site became New York's first state historic site — the card carries a penciled message to "Minnie" from what appears to be a family member, a small human thread connecting the Progressive Era to this founding-era landmark.
