Stars: they’re just like us. And, Hollywood photographer Sid Avery was the first to show that to the world. Avery captured the private moments of Hollywood’s biggest celebrities, including Marilyn Monroe, James Dean, Audrey Hepburn, and Elizabeth Taylor, proving they were more than just the glamorous people they appeared on the big screen. On Saturday, to mark the 75th year since he took his first celebrity photo, mptv (a photo agency Avery founded to help preserve photographer’s images) will host a one-day exhibition and sale of Avery’s most iconic photos. Here, Audrey Hepburn is seen on the Paramount lot with her pet dog, Famous, in 1957.
