Taking to social media, Ohanian proudly showcased a prized possession from one of tennis’ brightest young stars, Carlos Alcaraz. The entrepreneur posted a photo of a 2022 NetPro Limitless match-worn autograph card featuring the Spanish sensation. The collectible, graded and authenticated by PSA/DNA, includes a piece of Alcaraz’s match-worn gear along with his signature. Making it even more exclusive, the card is numbered 026/100.
Captioning the image with enthusiasm, Williams’ husband, who is worth $150M according to sources, made it clear that this is not just another item in his vast collection, but something he truly cherishes. He wrote on his Instagram story:
“This one is staying in my vault for a loooong time,” Serena Williams’ husband wrote.
