I have no idea. You see what I have seen. I doubt it, unless it was a very small amount of glue and a weak one at that. Glued cards usually see much more damage or show more evidence. It looks to me like some water staining possibly or maybe just dirt. There appears to be minor paper/print loss near his last name/team name.
If I can make time to swing by the shop before the weekend, I will try to view the card in person.
This is NOT my card nor do I have it in my possession, in case there is some confusion.
