Cooper Flagg, Kon Knueppel 1-of-1 Card with Game-Worn Shoes Revealed by Topps After Epic Duel

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.

The dual Kon Knueppel / Cooper Flagg card is available for purchase for 48 hours until the sale closes 5 p.m. ET on Feb. 1, according to Topps.

The first NBA matchup between Flagg and Knueppel was a historic game for both former Duke teammates.

Flagg became the youngest player to post 49 points in a single game while shooting 20-for-29 from the field and adding 10 rebounds in the loss to the Hornets.

Knueppel meanwhile set a new career high by racking up 34 points on 10-for-16 shooting from the field while going 6-for-6 from the foul line, including for two game-winning last-second free throws.
