As I mentioned a few days ago, I had some autographed in person Mariano Rivera 8x10's stickered and certed by GAI a number of years ago.  At the time, it seemed like the right thing to do for any future owner of the photos.  Then GAI imploded and items with their sticker are like death as we all know.  So, I asked a few days ago if anyone had an idea how to remove those doggone stickers.  Someone reccomended I get some Goo Gone and try to work that under the edge.  Well, that really doesn't…
