There's a racing section here that has some great info. I've just gotten into racing cards this last year or so. It's an interesting field, still relatively wide open as compared to a more established sport. The new stuff suffers from all the same nonsense as modern shiny baseball does. The older cards are a fun hunt. F1 cards go back to the interwar period and there are a lot of UK issues of consequence in the immediate postwar era. Lots of shiny too.
Here is a 2021 Topps Now F1 Hamilton-Verstappen:
IndyCar is the same as F1, effectively, but more fun because the drivers and teams seem a lot more down to earth and it is an American circuit. F1 runs a few now in the USA. Drivers from F1 and Indy often cross over. Mario Andretti won at Indy and at F1.
Indy:
--1962 Marhoefer Meats Rodger Ward signed card:
Lots of great Indy PCs and picture packs out there going back to the 1940s
--1969 IMSC Mario Andretti PC:
NASCAR is the most fun of all--they are allowed to make contact. At 170-180 mph. Highly competitive with lots of different winners, lead changes, etc. NASCAR cards started around either 1962 (if you count postcards) or 1972:
--1962 Richard Petty (with his father Lee) 'rookie' postcard:
--1972 STP Richard Petty 'rookie card:
--1979 Dale Earnhardt Sr. rookie PC:
--2023 Panini Kyle Larson signed card:
Yes that is the LA Coliseum; the last few years NASCAR has run a half-mile oval race in there.
