By David S. Lifton. Lifton's specific theory involves the alteration of JFK's remains between Dallas and Bethesda, and while I'm not sure he needed this many pages to get there, the good news is, you can use the book as a doorstop too. This book was a BFD in its time, though I confess I'd never heard of it until hunting around for gag gifts for my esteemed co-EIC at the Best Evidence newsletter.
This particular copy of the paperback edition is in pretty good shape, comparatively: a couple of faint spine cracks; mild shelfwear and rubbing to the covers. Clean and neat inside, though; pages are toned, especially the insides of the covers, but said pages are snug and unmarked, no dog-ears. A solid reading or research copy of this rarity.
