I am going to make a pretty sure good guess. 2002 National Sports Collector Convention at Donald E. Stevens Convention Center in Rosemont (Chicago). But there were 89 players past and current (then) signing. I can't find a list of them though. I remember standing in long lines to get autographs at that show.
