FILE - In this Feb. 24, 2010, file photo, some of 50,000 trading cards showing thoroughbreds Rachel Alexandra and Zenyatta are examined at Arkansas Graphics in Little Rock, Ark. The cards were printed to provide free souvenirs of the $5 million Apple Blossom Invitational horse race at Oaklawn Park in Hot Springs, Ark., but Rachel Alexandra's owner pulled out.
