Baseball:
Any and all Chicago Cubs, current and on-track HOF'ers, current stars and some Vintage
Basketball:
80's and 90's Stars, lots of random guys in the PC; some modern
Football:
Indianapolis Colts: Jonathon Taylor, Michael Pittman Jr., Darius Leonard, Peyton Manning; current stars
As of Nov. 2023, I'm currently building the 1978 Topps Set (my birth-year set) and picking up, primarily, Cubs cards and former Fort Wayne TinCaps players.
