In this circa-1966 graphic, we see the original name of a prospective west side residential development. It was to be known as "PARIS 2". This incited the ire of Parisian politicians, who threatened to initiate legal action. By the way, the slogan at the top translates to "A City Is Born".

The name of the planned community was quickly changed to PARLY 2. This was an amalgamation of PAR (taken from "Paris") and LY (from Marly-le-Roi, a nearby community).
