She's still the iconic image of the Hollywood blonde, even 47 years after her death – at age 36 – in 1962. With Monday marking what would have been the 83rd birthday of Marilyn Monroe, LIFE.com has posted a gallery of never-before-seen images of the then-rising star, taken in 1950 by Life photographer Ed Clark in Los Angeles's Griffith Park.

Monroe, then 24, had already played the girlfriend of a crooked lawyer in The Asphalt Jungle and was soon to be seen as "a graduate of the Copacabana school of dramatic art" in the Oscar-winning All About Eve. Still ahead: the subway-swept skirt in 1955's The Seven-Year Itch and her definitive comic performance, in 1959's Some Like It Hot, to say nothing of the inspiration she continues to provide Madonna and Gwen Stefani.

It's hard to believe she would be that old. I liked her performances in "Bus Stop" and "Some Like It Hot."
