By Gil and Ann Chapman. “Why did the Warren Commission disregard this evidence?” Probably because said evidence is a bit slender and amateurish, but having not read this slender PB myself, I can’t say.
I CAN say this 1967 printing is in pretty good shape for its age: mild edgewear, some page toning particularly to the covers’ insides, but uncracked spine, sits straight, no marks or dog-ears inside. A fine reading copy of a lesser case light.
