Here is an Official MBL 1993 All Star Game Baseball that was played in Baltimore.  This ball has autographs claimed to be by The Rolling Stones when I originally purchased it at a card show in Houston, TX on December 5, 1998.  I recently had this ball and authographs examined by Piece of the Past, Inc. in Las Vegas.  They found too many inconsistencies with these autographs to say they are genuine.  The ball itself is authentic.  It has been an interesting conversation piece around the house over the years.  Thanks for looking and good luck with your bids!!
