2002 Fleer Fall Classic, Rival Factions, Game Used Dual Relics ⭐ Frankie Frisch & Duke Snider
Fleer's “Rival Factions” name is more about curating Hall of Fame dual relic storytelling than actual rivalry history.
"The Fordham Flash" vs. "The Duke of Flatbush" is one of those “across-the-era NL icons” pairings designed to give the set historical depth and recognizable names on both sides of the card.
Fleer is basically pairing “old-school NL greatness” vs “mid-century NL greatness”.
Frisch = early NL dynasty Cardinals identity (inside baseball, contact era, managerial legend later).

Snider = postwar Dodgers slugger and face of Brooklyn/LA transition era.
