Friend's Sports Memorabilia

I know an online friend who loves sports memorabilia, and from what he told me, he already has some golf memorabilia and boxing memorabilia in his collection. He loves playing golf, so I'm assuming that he has more of those, but I remember distinctly that said he'd love to get (or buy, perhaps) his brother's autographed football. Yes, they are both sports fanatics, including their Dad! I'm not too sure about their Mom, though. I'm sure that with three male in the house, she'd be used to seeing sports related stuffs all over their place. But hey, I think she plays tennis, too ... :)
