Tall tassel-draped poles in vermillion and gold parade down the Avenue of Progress at the Panama-Pacific International Exposition of 1915, San Francisco — one of history's most celebrated world's fairs, staged to announce the city's triumphant resurrection after the 1906 earthquake and to commemorate the opening of the Panama Canal. Dragon-tree palms, colorful heraldic banners, and the colossal Palace of Machinery (967 feet long, the largest individual building at the fair) flank the broad promenade where a lone gentleman in a derby strolls in elegant solitude, capturing the optimistic grandeur of the Beaux-Arts "Jewel City." Published by Pacific Novelty Co. of San Francisco and Los Angeles, this card is a vivid artifact of an exposition that drew nearly nineteen million visitors in just ten months.
