Mr. Hall:Brilliant material. Thank You. I never even heard of this. This isn't taught in history books, or easy to find.Photos of Abraham Lincoln, Ulysses S. Grant, and others were being altered back in the 1860's, and quite well at that.Now do you think there's a chance that JFK, LHO, the Zapruder film, and other photos could have been altered in the 1960's, 100 years later ?I'm no professional photographer, but I know that photography, equipment, and tricks have developed a lot in the last 10 - 20 years alone.
