A new visit to Palm Springs, Calif., begins with an item guaranteed to capture the interest of fans of classic television. It's a coat that was worn by Archie Bunker -- the iconic character played by Carroll O'Connor -- early in the run of producer Norman Lear's legendary comedy series "All in the Family."
