Best Player to retire in 1971. Ernie Banks (Hall of Famer)
Did he have a 1972 card? No.
The last card of Banks was from 1971 Topps.
Was a “retro” card ever produced? Yes – somewhat inadvertently. Topps inserted mini versions of 1972 Topps cards into the 2013 product, and they included Banks in that set. It’s shown above.
Apologies to: Jim Bunning (Hall of Famer). His last card was in 1971 as well. No retro cards made of him, however.
