If you see a group of elderly women in red Tuesday on Capitol Hill, you’ve seen the original “Rosie the Riveters.”

About 30 women who assisted in the war effort during World War II stopped by the Capitol building Tuesday. The women are on a trip to Washington from Detroit organized to recognize their service. They’ll meet lawmakers and tour D.C. monuments before returning to Michigan the way they came, on an Honor Flight.

As the Associated Press reports, the group has received a warm welcome:

Dozens of flag-waving, sign-toting well-wishers greeted the women as they arrived at Ronald Reagan Washington National Airport. A children’s choir sang patriotic songs and the onlookers cheered as each woman emerged.

During World War II, women worked at jobs traditionally done by men, such as at the Willow Run plant in Michigan churning out bombers. One of them, Rose Will Monroe, was the inspiration for the Rosie character that came to symbolize female empowerment and the “we’re in this together” spirit of the American home front.

Coinciding with the visit, the House on Tuesday is expected to pass a bill to allow the remains of women who served in the Women’s Airforce Service Pilots to be interred in Arlington National Cemetery.

Here are a few shots from Capitol Hill posted by lawmakers:
