The 1988 stickers have the team name on the top which has a completely white background. However, a few teams can be found where there is a red strip across the top. While at first it may appear that this is just the result of a miscut sticker, if you take a closer look, you can see that the more common solid white top has a larger white space compared to the sticker with the red strip:
With the help of fellow Fleer collector Albert who has passed along information on some of the variations he has come across, it now appears that there are 12 stickers which can be found with the red strip at the top.
Both Colts variations (with the team name in small letters / large letters) have the red strip
If anyone is aware of any other stickers from this set having the red strip at the top, I'd appreciate hearing from you.
