Horse-drawn wagons still ruled Main Street when someone tucked this ingenious little accordion pull-out into an envelope and mailed it from Penn Yan, New York — a Finger Lakes village whose very name blends "Pennsylvania" settlers with "Yankees" in one improbable word. The cover image, a sweeping view down a telegraph-pole-lined Main Street circa 1905, is printed in crisp monochrome photogravure; bare-branched elms frame a storefront whose partial signage hints at a theater marquee. A decorative brass clasp closure — the very feature protected by U.S. Patent No. 806,631, granted December 5, 1905 — locks a concertina strip of miniature local views inside, including the Public Library and other civic landmarks. The patent date anchors the card precisely, making it one of the earliest examples of this novelty format. Collectors prize Penn Yan material for its scarcity; the Finger Lakes region generated far fewer souvenir sets than Niagara or the Catskills, and intact leporello closures are notoriously fragile.
