It’s from a postcard representing the Golden Gate and the Panama Pacific International Exposition that took place in the Marina District of San Francisco in 1915. Albert Bender helped make insurance arrangements for the fair. Anne Bremer exhibited five paintings and was awarded a Bronze Medal.
A portion of the dome and arcade of the Palace of Fine Arts (where Anne’s work was shown) is at the lower left of the image. The Palace of Fine Arts was designed by Bernard Maybeck and still stands today, the only remnant of the exposition, after a series of restorations.
