I found this Lebron James autographed jersey on ebay and it is authenticated by ABC memorabilia.  I wasn't really sure if it was a legit company and I looked it up but I still can't tell.  As for the autograph, the signature doesn't look mechanical but I still want to be positive it is authentic because the L in the autograph isn't like other Lebrons I have seen.  Any input would be greatly appreciated.
