HARTFORD, Connecticut (AP) — Mary Doyle Keefe, the model for Norman Rockwell’s iconic 1943 Rosie the Riveter painting that symbolized the millions of American women who went to work on the home front during World War II, has died. She was 92.

Keefe died April 21 in Connecticut, after a brief illness, said her daughter, Mary Ellen Keefe.

Keefe grew up in Vermont, where she met Rockwell and posed for his painting when she was a 19-year-old telephone operator. The painting was on the cover of the Saturday Evening Post on May 29, 1943.

Although Keefe was petite, Rockwell’s Rosie the Riveter had large arms, hands and shoulders. The painting shows the red-haired Rosie in blue jean work overalls sitting down, with a sandwich in her left hand, her right arm atop a lunchbox with the name “Rosie” on it, a rivet gun on her lap and her feet resting on a copy of Adolf Hitler’s manifesto Mein Kampf. The entire background is a waving American flag.

Rockwell wanted Rosie to show strength and modeled her body on Michelangelo’s Isaiah, which is on the ceiling of the Sistine Chapel.

Keefe, who never riveted herself, was paid $5 for each of two mornings she posed for Rockwell and his photographer, Gene Pelham, whose pictures Rockwell used when he painted.

“You sit there and he takes all these pictures,” Keefe told The Associated Press in 2002. “They called me again to come back because he wanted me in a blue shirt and asked if I could wear penny loafers.”

Twenty-four years after she posed, Rockwell sent her a letter calling her the most beautiful woman he’d ever seen and apologizing for the hefty body in the painting.

“I did have to make you into a sort of a giant,” he wrote.

The Rosie painting — not to be confused with a poster by a Pittsburgh artist depicting a woman flexing her arm under the words “We Can Do It” — would later be used in a nationwide effort to sell war bonds.

The painting is now part of the permanent collection at the Crystal Bridges Museum of American Art in Bentonville, Arkansas.
