Another day, another NFT. This time tennis superstar Naomi Osaka has joined the NFT game, but it's not in the way you would expect. Osaka together with her sister Mari Osaka is auctioning off a set of original art.

The collection titled “The Colors of Naomi Osaka” features artwork by Mari that showcases "the many shades of Naomi’s personality and character through heartfelt bursts of color." Each artwork is signed by both sisters and will be auctioned off on Basic.Space. However, a sixth and final artwork will be raffled off for $5 per entry, with all proceeds going to The Play Academy by Naomi Osaka, a charity founded by the tennis star with the goal of keeping young girls fit and active in sport through grants, coaching and events.

If charity and having a signed Osaka artwork isn't enough, fans of the player will also be excited to know that each raffle winner will win a custom set of Naomi’s Nike line curated by Naomi herself. How's that for motivating people into bidding on an NFT?

“As lovers, creators and curators of art since we were young, Mari and I are very excited to formally enter the world of art through NFTs," said Naomi Osaka. "I wanted to do things a little bit differently than the norm and make it more personal, which is why I asked my sister to create the pieces with me and offer something unique and special to fans and collectors from around the world, art that represents who we are and what we stand for. We hope that these one-of-a-kind pieces of art and the charitable aspect of the raffle will inspire people to dream big and to do better in the world."

"The Colors of Naomi Osaka" auction and raffle begins today, April 16, and will end on Friday, April 23 on Basic.Space.
