1967 Champion Tractor Spark Plugs & David Brown 1200 Tractor Ad

This original 8.5 x 11" magazine page from 1967 features a Champion Tractor Spark Plug ad on the front and a rare David Brown 1200 tractor ad on the reverse side.  Unfortunately their is a moisture stain on the lower edge of the page that impacts both ads slightly as can be seen in the photo capture.
