2004 Justice League Parade Car, Monte Carlo. This is a very rare 1-24th scale diecast as only 288 were ever produced and this particular on was autographed by Kurt Busch and Matt Kenseth.
This is actually a two car set. There is the 1/24th scale and a 1/64th scale care as well.
This is a Team Caliber preferred diecast and what that means if you don't already know that very special attention to detail was paid as the car was being designed and produced.
