This photograph, from a viewbook of the Panama Pacific International Exposition held in San Francisco in 1915, offers another interior view of the colonnade of the Palace of Fine Arts. In this photo, the size of the visitors walking the ambulatory suggests the magnificent scale of the structure. Sculptures can also be seen in the landscaping.
