# A unique collection of NFTs
**The Ballman project** is a collection of unique NFT tennis players created by **Stanislas Wawrinka** (three-time Grand Slam Winner, Olympic champion and Davis Cup winner). Each NFT has its own characteristics: mindset, conditioning, tactics, technique, power.
When it’s time for the reveal, collectors/players discover the characteristics given to their randomly assigned NFT.
These player characteristics aren’t necessarily fixed: they may change over time depending on how they do in tournaments.
