In 1952, Marilyn Monroe was grand marshal at the parade preceding the Miss America pageant in Atlantic City. Some remarkable images were taken along the route, images which showed how magnetic and carefree Marilyn was. I know Marilyn wasn't a porn star but I do know that some porn starlets admire her. Click below on this remarkable youtube clip for the images:

P.S. If I'm not mistaken, Hugh Hefner took one of these images and put it on the cover of the first issue of Playboy. The rest, as they say, is history.
