Hi CarPosters,
Very cool poster, and thanks for sharing it with us - and taking the time to help celebrate the Cougar’s 50th Anniversary 
Just a few items to note;
1969 Cougar Eliminator 351
1969 Cougar Eliminator 429
1970 Cougar 428
1970 Cougar XR-7
1970 Cougar Eliminator (Cleveland 351)
Technically, there were no 1969 Cougar Eliminator 429’s built. The two 1969 Boss 429 Cougars were not Eliminators.
Also, your choice of colors for the 1969 Eliminators is not quite right - they appear to be Competition Gold and Competition Blue, but neither color was used on the 1969 Eliminator (factory Eliminator colors in '69 were limited to: Bright Yellow, White, Competition Orange and Bright Blue Metallic).
The 1970 Cougar XR-7 would not have had a rear spoiler. That was an “Eliminator only” piece ~ although available over the counter as well.
If you are interested in getting feedback on the text, I’m sure we would be happy to oblige!
Still a cool poster - and thanks for making it and showing it to us!
