A woman in period dress stands dwarfed beside towering Saguaro cacti in the Sonoran Desert outside Tucson, Arizona, in this real photo postcard from La Luna Studio — the giant cactus was already a signature symbol of the American Southwest by the time this card was made. A handwritten caption on the back pins the location to "Painted Rocks" near Tucson, and the clothing style dates the scene to the late 1910s.
