The companion to the book by David S. Lifton, this 35-minute tape features interviews with "key witnesses," as well as "Kennedy autopsy photographs and x-rays."
The fact that the "research" gives away its best stuff right on the back of the box means this is probably more of a gag gift/display memento for the JFK-assassination obsessive in your life -- but as such, the box is in decent shape (some wear from storage; see pics), and while I haven't tested it, the tape should work fine if you have the technology.
