Indy got cards periodically in the 1960s through the mid-2000s, with A&S Racing producing the most sets, one annually from 1983 through 1987, although I don't have a single card from any of these sets. I have heard that they were the same company, restructured, that was known as All-World in 1991 and 1992, but I cannot confirm that.
Here is a brief rundown of the card sets that ARE in my collection. If the names are clickable, you can see the entire set on the Database.
1991 All-World. A 100-card set, I have the complete set, which I got in factory set form. This set chronicles the 1990 season with a couple of cards set aside for historical coverage, several of them honoring drivers who had recently passed away.
1991 Collegiate Collection Legends of Indy A 101 card set, with one card only available by mail order, and significantly harder to find. (and the only one I am missing). This set chronicles the history of the Indy 500, with highlights of most years included. An excellent set.
1992 All World Indy was also a 100-card set, but unlike the 1991 issue, this set focuses on driver photos only, with only one card in the set having race action- the checklist. It has a "Where are they now?" subset and was the first card set to include autograph of Indy drivers, although the autographs are simply one of the 1991 All-World cards that has been autographed, with no way to tell if it was pack issued or in person autographed. I pulled Tony Bettenhausen from my box. I have the complete base set. There is also a version of this set with French text, I do not know if it was issued for France or Canada. I was given several packs of them but the cards have all fused into bricks, unfortunately.
1993 Hi Tech Indy 500 was an 81 card set. Half of them featured action photos, and the other half featured a usually staged but sometimes cropped photo of the driver in front of a brick design with a neon pink Indy design. Because it was 1993, of course! I have 11 of the cards in this set.
1995 Skybox Indy 500 is a 112 card set, made up of the "Tall boy" style cards that are so hard to store. (I am not a fan of them in any sport or non-sport issue). It features photos of each car, driver, and race action. The oversize cards do lead to large, clear photos however. I have only 12 of the 112 cards.
2001 Checkered Flag Collectibles was a 2 card set consisting of Mario and Michael Andretti. It appears they were issued in some sort of partnership with Firestone. These are thick, well-made cards that are very similar in texture and production quality as early Flair cards. I have both of them.
