The wait is finally over. One of the longest standing NASCAR traditions finally returns on Sunday as the Sprint Cup Series gears up to run the Bojangles' Southern 500 at Darlington Raceway on Labor Day weekend.

The Southern 500 was the first ever 500-mile stock car race, and was a staple on Labor Day weekend from 1950 until 2003, when NASCAR moved the date. After much backlash from the fans and a reshuffling of the schedule, NASCAR has finally returned the Southern 500 to its tradition date.

To honor the tradition of the iconic event, the majority of the circuit has gone retro for this weekend with throwback paint schemes, team uniforms and even driver facial hair.

There are a host of NASCAR Hall of Fame members scheduled to be at the track Sunday, and the excitement both in the garage and among the fans is palpable.

To see all of the throwback paint schemes and their inspirations, check out this complete photo gallery before Sunday's race.
