As Amelia Earhart prepared to make history as the first woman to fly around the world, she staged a photo shoot to commemorate the occasion. We’ve seen numerous images of Amelia from that spring day in 1937, shots taken by her personal photographer Albert Bresnik, which have become part of the aviatrix’s legacy. But what we didn’t know is that Albert’s brother John, who was also present that day, took some film, which has recently been released.

According to the Associated Press, the grainy film, which is just a couple of minutes long, was taken with a 16-millimeter camera and had been sitting on a shelf in John’s office for more than 50 years. It wasn’t until his death in 1992 that his son, also named John, discovered the rare treasure.

“I didn’t even know what was on the film until my dad died and I took it home and watched it,” Bresnik said. “It just always sat it in a plain box on a shelf in his office, and on the outside it said, `Amelia Earhart, Burbank Airport, 1937.'”

The film reel, which was given to The Paragon Agency publishing house, has inspired a new book called, “Amelia Earhart’s Last Photo Shoot,” by Nicole Swinford that documents Amelia’s journey using never-before-seen images from that day.

Although there is some speculation as to the exact date the film was shot, there is little doubt that these are the last moving images ever taken of Amelia Earhart before her fateful flight.
