Yup, so some photo matching of say old jerseys, or autographs, photograph's maybe not be 100 percent positive authentic--the way I read some posts, photo matching, is only a opinion not a fact.

I'm still curious how can any photo expert determine any positive ID only with the ears -- are ears shapes the only critical parameter for facial recognition, to say open your cell phones.
