A tiny brass swing-clasp holds a secret on this 1907 novelty souvenir mail card — the front panel folds open to reveal a second view, a patented mechanical conceit (Dec. 5, 1905, No. 806631) that delighted Edwardian travelers along the Housatonic Valley. The black-and-white photographic image captures the Berkshire Inn and its neighbors in Great Barrington and Stockbridge, Massachusetts, tree-shaded verandas hinting at a genteel summer retreat in the hills. On the image side, in looping cursive, a woman named Edna has written to someone at Wellesley: "I thought of you at Wellesley. Please think of me here." — dated July 30, '07 — a wistful collegiate greeting between friends during the golden age of the picture postcard. The back is printed by Rotograph Co., N.Y. City (Germany), one cent postage to all countries, card no. 57601, inventory penciled no. 497. The brass clasp is intact and functional, a remarkable survival after 117 years.
