One collector who purchases a Topps trading card commemorating Cooper Flagg and Kon Knueppel's first NBA matchup will receive a 1-of-1 autographed card featuring scraps of their game-worn sneakers.
Topps revealed a first look at the game-used sneaker card after Knueppel and the Charlotte Hornets claimed a 121-121 win over Flagg and the host Dallas Mavericks on Thursday night.
