ANTIQUES ROADSHOW wraps up its visit to star-studded Palm Springs, California, with some star gazing - of the celestial kind - through the history and collecting of celestial maps. ROADSHOW appraisers at the Palm Springs Convention Center thank their lucky stars for the discovery of a 1956 signed photo of the guest at 10 years old, posed between baseball Hall of Famers Jackie Robinson and Roy Campanella - pioneers in breaking the color barrier in Major League Baseball - valued at $6,000 to $8,000.
