Elizabeth and Marilyn Watson, probably in the Berkeley, California, area, 1921, by Dorothea Lange, via Museum of Photographic Arts Commons on flickr (all photos here).
Above, Marilyn Watson; in both photos, the sisters seem to be under a grape arbor. Below, they are with their mother, May V. Landis Watson, still outdoors, I believe.
In 1921, Lange was 26 years old and running her own portrait studio in Berkeley. She had many well-to-do clients, as the Watsons appear to be. Ten years later, she would begin the work that made her famous: capturing the faces of the Great Depression and of the WWII internment of Japanese-Americans.
There’s a little clip from a PBS documentary on Lange here. It shows a number of her early photographs.
Grape vines over the porch of an old outbuilding at Struan, Arden, North Carolina, 1938, by Frances Benjamin Johnston, via Library of Congress Prints and Photographs Division.
Detail of the above; note the potted plants on the old ladder.
By the time Johnston photographed the old plantation of Struan for her Carnegie Survey of the Architecture of the South, the property had been a school for boys, Christ School, for 38 years.
