You are buying a vintage and very rare 1966 Castrol Oil ad celebrating the Shelby American Cobras winning the GT World Championship in 1965.  Better than the original flimsy magazine ad, the original ad is printed full size on 8 1/2 X 11 Brochure & Flyer Paper Matte.  Neat Ford Cobra ad is perfect for framing and will look great with a navy blue, red or dark green mat hanging in your den, office or shop.  See my store for other interesting motoring memorabilia, including many photos of original Cobras, Mustangs and Ford GTs racing in the Vintage Auto Racing Photos section.  Buyer pays $3.95 shipping in continental U.S.  Print will be placed inside a plastic sleeve and shipped with cardboard inside a large manila envelope to insure its safety. I do combine shipping.  Thanks for looking!
