She's muscled and serious. She's hard at work. She's wearing a red bandana and a blue jumpsuit. She's Rosie the Riveter, an icon that symbolizes the many women who jumped into munitions assembly lines, showed up at navy yards, took to the fields for harvesting, and put themselves on the front lines as nurses, all as part of the war efforts during World War 1 and World War 2. Thanks to the US Library of Congress, we have a rich trove of photos of real-life Rosie the Riveters working hard on the home front and abroad. Check out this list for rare photos of women working during the World Wars.
