I was wondering if you had the original copy of the ad? If so, would it be possible for me to get a certified copy of the ad?
No, I only have the scanned-in copy. None of the ads Warren lifted were originals. They were all scanned in and added to the web site I referenced above.
However, the newspaper the ad came from was the Charleston Gazette (page 19) and the date was Saturday, June 8th, 1968 so you might be able to contact the paper itself (IF they're still around) and have them send you a certified copy of that page.
