1984 Corvette GM issued Showroom poster RARE!! The story behind this poster was that the owner said he purchased it directly from a GM dealership and that it was a GM produced 1984 Corvette poster. Says he paid $150.00 for it. This would be the first year for the C4 style Corvette. Note that there is a crack in the glass in the lower rt corner approx 1" long. I have attempted to authenticate the story but have not located another poster like this on line?? If anyone out there has info that is different than what I was told please let me know, Otherwise a rare poster that is very collectible.
