This is the Darrell Waltrip 25th Anniversary  six car set, including a seventh car.  All are NOS, they were new in 1997 and are in as new condition now, including some shop ware.  Each box is numbered 3536 by Revell.  The set includes the rare gold , silver ,cars, the red white blue car, Yellow /white, Red/white, and green/white A and green/white B.  This unique set has been in my cool, dry storage for 27 years!
