In January 1952, Marilyn Monroe won one of the first awards of her career: 'Best Young Box Office Personality' given by the Foreign Press Association of Hollywood (an ancestor of the group that hands out the Golden Globes today). LIFE photographer Loomis Dean was on the the job that night, but his pictures were never published. Now they are. See below and check out more photos of Marilyn on that night at LIFE.com.
