In his delightful book, "Upper West Side Story, A History and Guide," (Abbeville Press, 1989, Peter Salwen recounts how Ethel Agnes Zimmerman, a stenographer from Brooklyn, went to one of the Gershwin penthouses for an audition for a part in a play, "Girl Crazy" in 1930: "She didn’t know which was more thrilling - a shot at stardom or a glimspe of the fabulous Gershwin penthouse.

With pre-war construction, water vistas, and a convenient, central Upper West Side location, this is a desirable building.
