That is an absolutely Beautiful and Very Well Documented
L-88.
I was Lucky enough to have a 1968 L-88 Roadster. Unfortunately it was not well documented other than it started life as Corvette Bronze and when it was Raced it was painted Yellow. Then when Restored it was done in Black. It had all the proper L-88 stuff, Many experts looked the car over and could Not dispute it, But no one could verify it. I have pic's from when it was a race car, and some pic's from when I owned it. It now resides in North Carolina with a very happy new owner who like me, gets the Thrill of driving an L-88 with a much lower cost.
Good Luck With The Sale. I am sure some very lucky guy will be glad to add that to his collection.
Here's a shot of mine. Undocumented a color change (not what I would have done) but Fast with a Capital F and Fun too.
Here's a photo from a local show.
