If it is the pic of the green nova with girl..it looks like a 69. If my eyes aren't shot it looks like those bucket seats have headrests and that started I think in 69??? The pic is not an SS car...looks like a fancy 2 dr coupe. Those with better eyes may correct me..
it is the green one . I also have A small factory poster of a 70 and now that I have the 68 one from the gm photo store it is the same picture but was changed to look like A 70 it still has the 68 rear marker lights .also you could get headrest in 68 as an option.
