Azaleas blaze pink and crimson along a moss-draped path beside the still black water of the lake at Magnolia Plantation on the Ashley River — one of America's oldest and most storied gardens, rendered here in the luminous Phostint color process that made Detroit Publishing Company the gold standard of Edwardian pictorial postcards. A lone wooden rowboat rests at the bank beneath a massive, Spanish-moss-laden live oak, the very image of Southern Gothic romance. This card was mailed November 21, 1912, aboard the steamship S.S. Delaware, postmarked at sea, and sent to a Mrs. A. Campbell at 21 Knoll St., Roslindale, Massachusetts — a poignant cross-country note from a traveler whose message touches on finding the P.O. Tuesday and the beauty of the land.
