If you're hoping Doyle Brunson will sign a copy of Super System for you, good luck with that after the poker legend discovered his autograph is up for sale on eBay.
The 10-time World Series of Poker (WSOP) bracelet winner was perturbed to find out that multiple "fans" were attempting to flip his autograph on the e-commerce platform. As such, he understandably threatened to stop signing for his fans.
I just went to e-bay and saw where most of the autographs i've signed are on sale.
