“Kenneth Hall gives daughter Peggy a shower with garden hose in front of their [Tennessee Valley Authority] defense home, Sheffield, Alabama,” 1942, Arthur Rothstein, via Library of Congress Prints and Photographs Division.
The photo was archived as part of Melbourne’s Biggest Family Album in 2006.
Dorothy remembers on hot days they would put the sprinkler on and play, as there were no swimming pools. They wore “horrible knitted woollen bathers, they soaked up the water and got heavy and baggy.” The ladder against the tree was to pick apricots “which were so ripe and juicy the juice would run down your chin.”
