Hey, klyd - that is really cool. As a fellow sports fan, I can truly appreciate the treasures you posses. I watch a lot of those pawn shop/collectible shows and they are always stressing to try and get some concrete evidence of the autograph's integrity - a photo of celebrity signing, certificate of authenticity, etc. They always seem to throw a wet blanket on a collector's enthusiasm about the item they have autographed! I guess signed sports memorabilia is one of the most counterfeited/faked items out there? Any way - great collection!
