Topps did a great job of making the sticker as innocuous as possible.
This makes two John Ely autos now, with the other being on this photoshopped SI cover. The auto didn't come out great, as I met Ely before I fully understood what to get certain items signed with, color choices and the like. You can read about my encounter with John here, if that's something that would interest you.
Thanks for the auto and the '92 UD help Steve, glad I could contribute some cards to your various set needs!
