Flags snap in a crisp San Francisco breeze above the Maryland State Building at the Panama-Pacific International Exposition of 1915 — one of the great World's Fairs of the twentieth century, held to celebrate the completion of the Panama Canal and the city's triumphant rebuilding after the catastrophic 1906 earthquake. Maryland's pavilion was a faithful reproduction of the historic home of Charles Carroll of Carrollton, one of the last surviving signers of the Declaration of Independence; the back of this card proudly notes that connection, making it a piece of both World's Fair history and American founding-era commemoration. The colorful linen-style image — printed by Pacific Novelty Co. of San Francisco — shows a gleaming red-brick Georgian mansion dressed with bunting, the Stars and Stripes flying proudly overhead alongside what appears to be Maryland's state banner, while a vintage automobile and a crowd of fair-goers animate the foreground. A penciled "3–" in the stamp box likely indicates a dealer price notation. The card is unused and retains excellent color integrity.
