Another two of the scanned images are from a flyer. At first glance, I though the red at the top of the second page was the silhouette of a Mustang horse. The high part could be the ear and the lower part the mane. A subsequent look reveals that the profile of the top of the red graphic follows the profile of the bottom of the Mustang logo on the first page. It's just upside down.
After I had these scanned images for a little while, I received an email from someone who had an original flyer. He sent me some photos of the flyer and I was able really get an idea of what the flyer looks like. It is a tri-fold. When unfolded, I think it measures about the size of a legal sheet of paper (8 1/2" x 14").
Thanks to Jeff M. for providing the scanned dealer flyer images shown here. Also, thank to Bill C. for providing the photographs of an actual flyer.
