Each of the 1,336 Spurs NFTs is a digital re-creation of one of five hand-drawn play cards from Popovich combined with one of the five court designs that the Spurs have had during his reign. NFTs, or non-fungible tokens, are digital identifiers that can be used to show ownership of digitized assets such as a photo, video or audio file. Proceeds from the sale will be donated to the San Antonio Food Bank.
