Do you follow Topps on Twitter? You probably already know this,but just in case. They posted it earlier:
"Due to a printing error, Ultimate Gear and Autographed Ultimate Gear redemption cards in 2010 Topps UFC for UFC heavyweight Antonio Rodrigo Nogueira were produced and inserted into packs. These should have been for his twin brother, UFC Light Heavyweight Antonio Rogerio Nogueira. All redemptions for these two cards and their parallels will be honored for Ultimate Gear and Autographed Ultimate Gear cards of Antonio Rogerio Nogueira."
