In 2000 and 2001 TBS/D9 released two sets of trading cards, Back To The Glory and Back To The Glory II. The following cards are from the first Back To The Glory set. The set contained:
44 regular cards
44 silver variants
44 gold variants
The 44 includes 2 checklist cards
9 "Impression Replay" cards
9 "Kane on the Court" cards
42 "Hero's Signature" cards
2 "Piece of the Glory" cards (jersey pieces I believe)
Both BTTG sets and I believe most of the めんこスタジアム cards are focused on Pro Sportsman No. 1 rather than either SASUKE or the regular Kinniku Banzuke show.
I guess I picked up a pack of someone's extras at マンガ倉庫 one day. Click through to see the larger images.
