Knicks star Karl-Anthony Towns pulls rare, valuable Cooper Flagg rookie card at Topps NBA launch event

The card collecting craze got even bigger last week when Topps, a worldwide leader in trading cards, returned to the NBA with a new launch for the first time since the 2009-10 season. And one of the star players featured on the cards has already pulled a rare find. New York Knicks star center Karl-Anthony Towns, alongside teammates Josh Hart and OG Anunoby, were on hand at the NBA Store in Manhattan last Thursday for the Topps Basketball launch when he started to open packs up with Fanatics founder Michael Rubin, late-night host Seth Meyers and a select group of young Knicks fans. CLICK HERE F
