There, of course, are commercials that I don't have that I want. On 16mm (or 35mm) film.
The one thing that comes to mind first is the Iron Eyes Cody Keep America Beautiful commercials from 1971 - I'm interested in these.
"Give a hoot, don't pollute" as well.
I will add to this list as I think of more things I'm looking for.
Email me at wants @ in16mm.com (use film or 16mm in the subject so I know you're not spam) if you can help me find a source for these.
