In this September 15, 1954 publicity photo courtesy Running Press, Marilyn Monroe is shown during the "subway" scene of "The Seven Year Itch," filmed late in the evening on Lexington Avenue in New York. Monroe passed away a half-century ago this week, a murky death that remains one of Hollywood's most tantalizing mysteries. But look around: Her legend lives on, more vibrantly than ever. In a twist she surely would have appreciated, this 1950's bombshell has become a 21st-century pop culture phenom. (AP Photo/Courtesy Running Press)
