Card Identification Forum

I have a #77 Buhner in this series with "2001 Seattle MLB 2001 Fanfest"  foil stamped on the front.  There is a 2000 Chicago Sportsfest subset listed beneath the primary set, but not the 2001 Seattle.  Im confused because the Chicago 1998 card mentions a 2000 event.  What am I missing here?

From BaseballCardPedia [1]:

"Convention Parallels
Special parallels of the 1998 Donruss Signature Series set were produced for numerous conventions held in the United States from 1999-2001. These convention parallels were produced by Playoff and it is unclear why Playoff chose an old baseball product for this promotion, as they had neither an MLB Properties nor an MLBPA license at the time. These cards were not serial numbered and it is unclear if parallels exist for all 140 players in the set or if parallels were produced just for specific players. However, there are 11 Ken Griffey, Jr. convention parallels that exist, with each displaying a unique stamp representing its respective convention:

Sportsfest 1999 (June 17-20, Philadelphia, PA)
Sportsfest 1999 (August 19-22, Chicago, IL)
Superbowl XXXIV (January 26-30, Atlanta, GA)
Comic Con (July 15-18, San Diego, CA)
The 21st National (July 27-30, Anaheim, CA)
General Convention Show (August 6-9, Milwaukee, WI)
Sportsfest 2000 (August 18-20, Chicago, IL)
Wizard World Convention (August 27-30, Chicago, IL)
MLB All-Star FanFest (July 5-10, Seattle, WA)
Comic Con (July 19-22, San Diego, CA)
Wizard World Convention (August 17-19, Chicago, IL)"

Looks like we will need to add parallels once we have knowledge of checklists. I recommend opening Inaccuracy Reports as needed.

Are we positive Donruss was responsible for the stamping and distibution of these cards, or was it a third party after-market thing?
