I've got a 1938-1939 Ford bus from the opening theme of the Latin American version of Sesame Street known as "Plaza Sésamo." IMDb claims the show was created in 1973, but both Wikipedia and the official Sesame Street website claims it was made in 1972. This is why I'm hesitant to add the show directly to the page right now. Nevertheless, here are some links, and an image for the show.
