Does anyone know where the best place to buy legit signed football shirts? The missus is trying to get her brother one for his birthday and I've no idea where is any good. Places say they're legit and have COA's etc, but anyone can fake a signature and then knock up a certificate. I know the only way to be sure is to be there and see it for yourself, but surely there's some reputable sites/sellers out there? Looked on ebay and there's millions....
