This auction is for one used 1966-1967 Corvette grille.  I do not know if it is original or a reproduction, but it has less wear than I would expect for a grille that has been in a car for 50 years. 

There are some stone marks and there are some bubbles on the egg crate portion. The brackets are held in place with pop rivets, not smash rivets as original. I would call this a very nice driver quality grille.
