This is interesting because I’ve now gotten to the point where I’m doing sets from my Lifetime Topps project, so if there is a card that exists for the player in question, I probably have it!
Best Player to retire in 1979. Lou Brock.
Did he have a 1979 card? Sort of.
Brock retired as baseball’s all-time steals leader, and he reached 3,000 hits in his final season. He was featured on a card #1, a Highlight card, with Carl Yastrzemski. Yaz also reached that milestone (but didn’t retire) in 1979. Brock didn’t get a regular card, however.
Was a “retro” card ever produced? No – Topps hasn’t created any new cards showing Brock on a 1980 design. Uncle Doc’s Card Closet did, though!
Apologies to: Catfish Hunter didn’t have a 1980 Topps card, but he got a card in the 1980 portion of 2013’s Archives set. Another inadvertent “card that never was” produced in a Topps retro product! See that card above.
