Bernard Maybeck's Roman-rotunda masterpiece glows in warm terracotta and gold against a blue California sky, its colonnade reflected in the lagoon before it — photographed during the 1915 Panama-Pacific International Exposition in San Francisco, where this Palace of Fine Arts stood as the most beloved structure on the fairgrounds and the only one the city ultimately refused to demolish. Published by the Pacific Novelty Company of San Francisco (PNC), whose California grizzly bear logo anchors the reverse, this card carries catalog number X-153 and is printed in the early flat-back style with a single undivided address zone and a simple "STAMP" box — consistent with PNC's output during the fair's run (February–December 1915). The expo marked San Francisco's triumphant return from the 1906 earthquake and celebrated the opening of the Panama Canal; over 18 million visitors attended. The Palace was the only fair building saved; it was reconstructed in concrete in 1965 and still stands today. Cards from the 1915 PPIE are among the most collected California exposition ephemera, and PNC issues in this condition with clear publisher identification command consistent collector interest.
