America has National Baseball Card Day. Canada will spend February 21 observing the sacred "National Hockey Card Day".

To try and recruit more collectors, Upper Deck has produced a 15-card set, available nationwide only on that Saturday.

“We’re extremely excited about this upcoming NHL promotion,” said Josh Zusman, Upper Deck’s hockey brand manager. “As the league and the Players’ Association’s exclusive trading card licensee, it’s only fitting that Upper Deck should produce an exclusive set just for Canadian fans.”

The set, distributed via unopened packs, will include star rookies, superstars and legends. The cards, which spotlight Canadian-born NHL players, will be given away free of charge at hundreds of Canadian hobby specialty shops, as well as select retail locations.

The base set of 15 cards consists of three subsets and includes: “Canada’s Rookies” (Steven Stamkos, Kyle Turris, Josh Bailey, Colton Gilles and Derick Brassard); “Pride of Canada” (Sidney Crosby, Vincent Lecavalier, Jarome Iginla, Joe Sakic and Martin Brodeur); and “Hockey’s Heroes” (Wayne Gretzky, Mario Lemieux, Gordie Howe, Bobby Orr and Don Cherry). A special “National Hockey Card Day” logo-stamp will adorn each card front.
