This pack is O-Pee-Chee cards. Originally released in Canada, the company was originally a candy confectionery sold to Nestle in 1996. Eventually, Topps started releasing cards under the O-Pee-Chee name in 1997 until 2004. Upper Deck started putting cards out under the O-Pee-Chee brand in 2007. As for this pack, you could open it. I don't think it has any true value since they were just giving them away. There isn't anyone of note for rookies (Martin Brodeur, Pavel Bure, and Valeri Kamensk).
What?? No American Ninja Warrior cards or Ninja Warrior cards yet?? Someone is really slacking!!
