This card has baffeled me for 10 years since I pulled it. The card is serial numbered right and had the right deminsions for a mini card. The mini card is the same size as the 2007 standard set . I have provided scans of the front and back of the card but the question lies on the back for it is not a Green back but a Black back but the serial numbering is right for this particular set. If someone feels the back should not be submitted please feel free to reject the back of the card. I only have 1 card in this set of the HOF players
Looking on E-bay with Green backs it looks like they are all Black Backs with the correct serial numbering like these:
