Here's a pic of the poster:
From Hot Rod forums:
"Another movie is "Corky" starring Robert Blake. He drove across country in a 67-69 Barracuda that had aluminum slots, side pipes and a wild early 70's paint. Car also had a shortned superbird wing on the back as well. I have some pics of this car and will post them as well.
A little trivia: The car also starred in a Sears diehard commercial in the late 70's where the dad's car would not start so he had to take the son's Barracuda and as the dad was driving away he was stalling and bucking it because he could not drive a stick. "
