File:2011 HW Premiere, TM symbol or (R) symbol?.jpg

After I removed cars from their packages, I found that :


 * Above : Package/card of 2011 HW Premiere (New Models) MINI Challenge, 30/244, Base code D22, wrote 2011 HW PREMIERE®
 * Below : Package/card of 2011 HW Premiere (New Models) '63 Studebaker Champ, 29/244, Base code D22, wrote 2011 HW PREMIERE™

Many 2011 HW Premiere cards are use TM symbol. Are cards with ® symbol error or not?
