Greta Garbo would have been 100 today, and you don’t have to look far to find the celebrations of America’s most elusive diva. “Few personalities are cultural signposts. But in her heyday, Garbo inspired Cole Porter, who sang of her munificent salary in You’re the Top. Madonna paid tribute to Garbo’s giving good face in Vogue. Even fewer personalities become adjectives; Garboesque has come to mean aloof, mysterious, remote… Garbo left the screen in her prime (like Marilyn Monroe, who died at 36), thus the popular image we have of her is radiant, forever young.”
