Gleaming white under a patriotic summer sky, this faithful replica of George Washington's Mount Vernon — built by the YWCA for the 1926 Sesqui-Centennial International Exposition in Philadelphia — sits on a manicured lawn with its columned portico, cupola, and twin chimneys perfectly rendered in the hand-colored linen style of the era. The exposition ran from June 1 to December 1926, celebrating 150 years of American independence, and this card was the official souvenir postcard published by John D. Cardinell, the exposition's official publisher. The reverse carries the full Sesqui-Centennial branding — a Liberty Bell vignette flanked by "1776" and "1926," and the proud declaration that Philadelphia was "The Cradle of Liberty." The card was never mailed, preserving its rich color and crisp stock. American flags fly from a tall pole before the building, lending the scene a ceremonial grandeur that perfectly captures the nationalistic fervor of America's sesquicentennial year. Exposition topographical cards, particularly official publisher issues, are perennial collector favorites.
