A brass eyelet punched through the upper-right corner of this patriotic fold-out souvenir is the first clue that something clever is at work — pull the string and the accordion concertina of Washington D.C. landmarks cascades open, revealing a miniature gallery of hand-colored civic monuments that would have delighted any early-20th-century tourist. The cover, patented December 5, 1905 (No. 806631), shows the Capitol building in a vibrant hand-colored lithograph, its dome gleaming against a pale blue sky. Inside, a portrait of George Washington anchors the sequence, followed by the White House Main Entrance, the Library of Congress, the Washington Monument, and further landmarks — all rendered in the gentle pastels of early color printing. The card was mailed in March 1908 from Washington, D.C., franked with a 1-cent Franklin green stamp and routed through the postal system to a Miss N.M. in Steubenville, Ohio, postmarked on arrival. Published by The Rotograph Co. of New York City — one of the most prominent American souvenir postcard publishers of the Edwardian period — this is a textbook example of the mechanical novelty postcard format that captivated travelers during the Golden Age of postcards.
