Hey all- I am running a silent charity auction on Sat. June 13 (www.timharmon5k.org) . Received a donation of a framed double matted autographed photo of Clinton Portis of the Redskins. It also has a patch of game worn jersey and ball. It has a placque with the game date (Nov. 5, 2006) a victory against the Cowboys and says limited edition 82/300.

The photo has the following logos in the lower left hand corner:NFL, NFLPlayers, PhotoFile. In the right lower corner is a NFL logo hologram with the # 00182816088 printed on it.

On the back is a small sticker that says "Guaranteed Authentic by www.GameExclusives.com" Own a piece of the game

So is this real and if so how should I value it? Thanks for any assistance. I appreciate it!
