As you can see, Fleer didn't exactly stay up all night modifying their sticker insert designs from 1990 to 1991. Solid blue changed to a green-fading-to-yellow. Except we do see one huge difference. In 1990, these were merely 'Baseball Stickers'. By 1991, however, these innocent little logos graduated to ACTION SERIES stickers! Oh golly gosh look at all that ACTION!!! Back up, just BACK UP! When I decide to peel these off and place them on my Officially Licensed Fleer Mini-Album I'll be the actionyest kid on the block. Go Reds.
