This is a new, faithful reproduction of the rarely seen promo sticker that was created after the 1968 Cougar won Car and Driver magazine's Readers Choice Poll for Best Sporty Car. The winners were announced in the May 1968 issue. These were mostly put on the quarter window glass, but it's up to you where to show off your Cougar's status.
This new decal is the same size as the original (2-3/4" x 3-3/8") and printed on mirror-shiny vinyl. The main difference is that the adhesive is on the back side of this reproduction sticker, unlike the original, which could be applied from the inside. Luckily, these new decals are laminated with a UV protective gloss coat, which should keep them holding up well outside if needed.
