Celestrial Stars is an insert set in 2010 Topps Allen and Ginter. This 12-card set features current major league players born under specific zodiac sign with a short description of the supposed personality traits of people born under that sign. Somewhere Bill James has a list of the best players who are Leos, but the rest of us don't really care. The cards are mini-sized and were inserted randomly into hobby packs, typically 2 per case.
