Rob Steinmetz would be of most help here. However I do know that there are some Cubs jerseys void of the usual collar tagging. Mid season call ups, players acquired during the season in a trade come to mind. I believe Nomar Garciaparra had a jersey with no collar tagging when he was acquired but Rob Steinmetz is clearly the expert here and I will defer to him. Hopefully he will post something soon. But do not rule it out as being game worn/used just because it does not have traditional collar tagging. Rob?
