In June 1962, Marilyn Monroe arrived at Hotel Bel-Air for a 12-hour photoshoot with Bert Stern, yielding 2,571 portraits revealing an unreserved yet glamorous Monroe. Collectively called “The Last Sitting,” the portraits were the public’s final glimpse into her life as she died just six weeks later.

Guests and locals now have a chance to discover Stern’s series in a rare exhibition in the lobby of Hotel Bel-Air, Sept. 1–Oct. 31. The exhibition will feature 15 photos, including two double-sided, 8-foot-by-3-foot prints. A teaser with nine photos is on display in the lobby now.

“Bert captured Marilyn in a series of images so comprehensively,” said curator Shannah Laumeister Stern, wife of the late Stern. “He went beyond her external and ethereal beauty to her essence. Marilyn seemed to trust Bert and let go in ways she had never before. She was free and playful, and Bert captured the total of her with the reverence and passion he felt. They had a relationship through what they both related to most, the lens of the camera.”

The exhibition is complimentary and open seven days a week.
