Auto racing fans are among some of the most loyal and rabid fanbases in all of North American sports. These two 50-year-old vintage issues of Sports Illustrated are the perfect affordable addition to any auto racing collector's stash, and chronicle the two biggest events in the sport (Indy and Daytona) from a half-century ago. Both magazines have survived the half-century marvelously (a small tear on the bottom right corner of the Indy issue is visible in the photo). Recently unearthed in an estate, take a look at the photos and see just how wonderful they are.
