This is an unusual card for the Herschel Hoard, in that it doesn't feature an image of Herschel Walker, but rather, just mentions him.
What this is, is a ballot in trading card form, in which fans could vote for certain players for the 1998 N.F.L. Pro Bowl (from the just completed 1997 season). It was an insert set in the Stadium Club Football set that year.
Herschel had a good year returning kicks for Dallas, in what would be his final year in the league.
He returned 50 kickoffs for 1,167 yard, for an average return of 23.3 yards. His longest return was 49 yards.
Though he is listed as a nominee, he failed to make the Pro Bowl team.
I think he actually had a better season returning kicks in 1996, his first year back with the Cowboys. That season, he returned 27 kicks for 779 yards. That's an average of 28.9. His longest return that year was 89 yards.
This card is #36 in a 40 card set.
