1972 2-Page John Deere 16 Speed Tranny Vintage Ad #965

This original 2-Page magazine ad from 1972 is from a John Deere Ad Campaign I'm calling the Sound Reason.  This ad measures @ 13 x 20" when carefully aligned and fully open as shown in the image.  This particular ad talks about the John Deere 16 Speed Quad-Range Transmission on the 4230 and 4430 Tractors of the time.
