Every July for the past three summers, hundreds of motorcycle enthusiasts from around Europe have roared into Milmersdorf, Germany, north of Berlin, to share their love of all things motorized and two-wheeled. The Petrolettes festival is different than most biker gatherings, though: All of the celebrants are women and girls. The three-day fest, launched in 2016 by a group of female bikers called The Curves, is (in the Petrolettes' website's words) "a women-only, petrol-powered camp-out party weekend."

n May 30, 1943, the South Bend Blue Sox, Rockford Peaches, Kenosha Comets, and Racine Belles played the first official games in the history of the All-American Girls Professional Baseball League (AAGPBL). The Blue Sox eked out a 1-0 win over the Peaches in Rockford, and the Comets beat the Belles 8-6 in Racine. Over the next 12 years, those four teams became 15, and those two games became thousands, played by hundreds of women whose talents transformed America’s pastime. Though it folded after the 1954 season, the AAGPBL would be immortalized with a popular exhibit at the National Baseball Hall of Fame in Cooperstown in 1988, and a beloved film, “A League of Their Own,” in 1992. To mark the league’s 75th anniversary, Foto has pictures from its heyday.

Seventy-five years ago, on May 29, 1943, Norman Rockwell's iconic painting, "Rosie the Riveter," made its debut on the cover of the Saturday Evening Post. Donning a red bandana with a rivet gun on her lap and her foot resting comfortably atop a copy of "Mein Kampf,” Rockwell's Rosie (which he based on Michelangelo’s painting of Isaiah at the Sistine Chapel) remains a powerful symbol of American women and their critical contributions to the war effort. Here, photos taken between 1942 and 1943 at factories across the U.S. offer a glimpse of the hard-working women who kept America running when it needed them most.
